Reorder POI data update and trigger creation to avoid refresh of materialized view after update done by initial import.
I checked the other updates and there are OK.
Make a few more mappings declarative, and removes values declared in both SQL and the yaml file.
Here's the diff comparing `build/tileset.sql` in master vs the new PR. The changes are mostly stylistic, except when a nested `if` statement is expanded into individual `if ... and ...` conditions (logically identical)

Simplify some of the OSM->OMT field value mappings using declarative syntax.
This approach is not for all cases, but in many it removes
the need of storing the same field in both the .yaml and .sql files.
TODO: support more complex AND/OR cases
* rail stations
* Create 'railway' POI class with 'station' and 'halt' subclasses
* Introduce subway stops as POI
* Revert unwanted changes in .env and openmaptiles.yaml
* Remove halt key from documentation
* Distinguish aeroway and railway station, add tram_stop
