#1313 added `expressway` tagging to the transportation layer. However, this also added the `expressway` attributes to ramps where it doesn't make sense (ramps by definition are controlled-access roads in all cases). This PR corrects this by dropping the `expressway` attribute from ramps where it doesn't make sense to do so.

Omitted values include:
* office=yes ... too generic
* office=vacant ... not really a POI
* deprecated values (like office=administrative)
* tags that don't have a clear meaning (like office=camping,
office=healthcare, office=transport, office=design)
* tags where another tag is used more often, e.g:
office=religion is used more often than office=parish
office=construction_company is used more often than office=construction
office=engineer is used more often than office=engineering

This PR removes the `oneway` attribute from ferry lines and rail lines. These attributes don't really make sense for these feature classes and they are not typically rendered in general-purpose maps.
1) The trigger name has a typo of `trigger`, which is incorrectly spelled as `tigger` and doesn't match the following create command: `CREATE TRIGGER trigger_flag`. This may result in an error when invoking `make import-sql`.
```
ERROR: trigger "trigger_flag" for relation "osm_park_polygon_gen_z4" already exists
xargs: sh: exited with status 255; aborting
```
2) The `trigger_flag` may be created on the wrong target in line [#251](https://github.com/plainheart/openmaptiles/blob/master/layers/park/update_park_polygon.sql#L251).
This workshop is extremely helpful in understanding how OpenMapTiles works, especially in creating new layers, which is not properly documented (or I just couldn't find any documentation).
This PR restores missing transportation_name features that are missing from zoom 11 and improves the mechanism by which transportation_name features are merged through lower zooms. This prevents route features from being dropped due to bridge interleaving (when a bridge interrupts an otherwise continuous route).
This fix moves the length check to a later stage of processing and merges bridges/tunnels if they're too small. This is similar to the work done in the transportation layer to merge bridges that are too small to render lines. In this layer, bridges are merged when they're too small to justify a separate label.
This PR collapses housenumber values into the form min(housenumber)-max(housenumber) for cases where housenumber is a semi-colon separated list. If the list is all numbers, the bounds are the smallest and largest numbers. If the list includes non-numeric characters, it falls back to the first and last values in the list.
VectorTiles generated via the [openmaptiles-tools](https://github.com/openmaptiles/openmaptiles-tools) toolchain and using the OpenMaptiles-SQL-Layers as the query-source result in tiles which can contain duplicated keys.
This is because PostGIS `ST_AsMVT` is used to generate the Tiles and due to the way they [implemented parallelization](https://trac.osgeo.org/postgis/ticket/4310).
Although it is not prohibited by the Mapbox-Vector-Tile-Specification MapBox as well as MapLibre depending on version either throw a lot of warnings or even crash when encountering tiles with duplicated keys.

After investigating I identified the boundary layer in zoom-leves 1 - 4 as the only layers containing duplicated keys.
This PR addresses two main issues introduced by the new ID-Based Merged-LineString Updates
1. Partial Indexes can only be accessed when the query matches more or less exactly and the query-planner will fail to use indexes when targeted via the join-condition and not the where-condition
- `osm_transportation_merge_linestring_gen_z9`
- `osm_transportation_name_network`
- `osm_shipway_linestring`
- `osm_aerialway_linestring`
- `osm_waterway_linestring`
2. When intersecting updated Source-LineStrings with the existing Merged-LineStrings we join the Source-IDs of each existing Merged-LineString. This bloats the table unnecessarily and slows down bigger updates considerably.
- This is addressed by aggregating the Source-IDs of each existing Merged-LineString into an array and concatinating these arrays when grouping them. Afterwards we add the IDs of updated SourceLineStrings and deduplicate the result before adding it to the Source-IDs-Table.
LEAKPROOF requires the executing user to have superuser privileges when creating the functions which would be the only statement required to be executed as a superuser.
Fixes a typo analyzing the `name_changes` table during execution of `transportation_name.refresh_shipway_linestring` and `transportation_name.refresh_aerialway_linestring`
Paint shop is missing from the schema, so shops of this type do not appear on the map beside other POIs

Some parts of quickstart.sh reference `${area}.mbtiles`, but the file that gets created with the default `.env` is `tiles.mbtiles`. We should either reference `$MBTILES_FILE` instead, or override the filename with `${area}.mbtiles` (which is the approach taken by this PR).
Based on analysis from planet builds for this layer as well as running updates via the integrity script as discussed in #1516, these three indexes are not used and can be removed.
Multi-Column Primary-Keys (Unique-Constraints) must not contain NULL values in postgres up until version 15.
This PR coalesces NULL to empty strings for the primary columns during `transportation_route_member_coalesced` updates and import.
Additionally adds the missing `concurrency_index` to UPSERT statement of `transportation_route_member_coalesced`
This PR adds support for `boundary=aboriginal_lands` by adding it to the `park` layer. While these lands are certainly not "parks", they have similar treatment from a technology perspective and can benefit from the existing processing chain established in that layer. I set all of these objects to `class=aboriginal_lands` in the tiles, including at the lowest zoom in order to separate it from the protected area merging implemented in #1160. In order to distinguish these from general parks, I expose the `class` attribute for these objects at z4 and also ensure that the z4 generalization is performed separately for protected areas versus aboriginal lands.
This unblocks #ZeLonewolf/openstreetmap-americana#105, which describes why having indigenous land boundaries is an important general feature on the map. This is also consistent with my suggested implementation in https://github.com/openmaptiles/openmaptiles/issues/1296#issuecomment-967749403.

In some areas of the world, ship transportation is the main means of long-distance travel. For example, in Alaska, the [Alaska Marine Highway System](https://dot.alaska.gov/amhs/route.shtml) is the principal means of transportation through the Alaska Panhandle and down the Aleutian island chain. The AMHS carries the same importance that the Interstate Highway System has on land, and these ferry routes are exceptionally long distance.
This PR now removes bridge/tunnel/ford attributes from the `transportation` layer from sections of bridge/tunnel etc that are too small to be meaningfully visible at a particular zoom level. This allows those segments to be generalized into geometries along with the surrounding sections of road, thereby dropping lots of useless little pieces of geometry in lower-zoom tiles.
This PR changes the three-column unique index to an on-insert trigger. This should fix the issues we're having with CI failures and still achieve the behavior of coalescing duplicate routes.
I moved the concurrency_index calculation into an intermediate materialized view to separate the de-duplication capability from both DENSE_RANK() and from imposm updates.
This PR sets `surface=paved` for `highway=track` + `tracktype=grade1` if no other value of `surface` is set. Roads tagged in this way are [generally paved](https://wiki.openstreetmap.org/wiki/Key:tracktype) and therefore encoding them as a paved road is appropriate.
# Problem description
#1128 introduced route relation concurrency information in OpenMapTiles via the `route_X` attributes. The original implementation assumed that there would be a single route relation for each `network` and `ref` pair. However, it is increasingly common practice to tag a separate route relation for each direction of a route in order to provide awareness to routers and other data consumers of the directionality of a route. This standard and growing practice is described on the [OSM wiki page on route directions](https://wiki.openstreetmap.org/wiki/Route_directions). Thus, the naïve implementation of #1128 caused duplicate entries to be added as `route_X` attributes in the case where separate route relations were used for directional routes.
# Solution description
This PR adds grouping when computing route concurrency information, such that duplicate entries are coalesced in a predictable way. Since this grouping is done only within a route membership join of a single member way, the computational complexity should be trivial.
This PR adapts the code used in #1457 to allow POIs to render up to z10 for very large features. I set the threshold at a very conservative value of 10% of a tile. Thus, it will render if an area POI covers at least 10% of a tile at a given zoom. Only for 'university' and 'college'.
Additionally, this consolidates a double UNION ALL on the same table with a WHERE/CASE combination, which is simpler.
This PR adds eight missing languages, all of which are among the top 25 languages spoken in the United States, as discussed in ZeLonewolf/openstreetmap-americana#586, and have at least 10,000 `name:xx` usages in the database. Additionally, most of these languages are the primary or national language in the countries where they are most commonly spoken.
This PR introduces simple filtering of duplicate housenumbers.
Simple means that filtering is done withing the tile.
Duplicates are defined as same housenumber, street, block_number[1].
Duplicates are usually caused by POIs. People like to add addresses to them. Most POIs have names so to prioritize addresses we pick features without names first.
Formula is: `row_number() OVER(PARTITION BY concat(street, block_number, housenumber) ORDER BY has_name ASC) == 1`
This PR reduces the minimum lake line zoom to z3, allowing the largest lakes to show a renderable label. The lakeline function is restricted by the LineLabel() function, which limits lakelines to only those that are big enough to render a text label. Therefore, further restricting lakelines by zoom is not necessary.
