Maptiler custom map ids are only useable by the account that create them. So if we hardcode them forkers won't be able to use the maps even if the bring in their own api key (because they can't access our maps with their api key).
Requires to set our map ids in `local.properties` for local development:
```
services.maptiler.lightMapId=9bc819c8-e627-474a-a348-ec144fe3d810
services.maptiler.darkMapId=dea61faf-292b-4774-9660-58fcef89a7f3
```
