Review necessity of better-sqlite3 dependency

Feature Request

Is your feature request related to a problem? Please describe.
Managing better-sqlite3 dependency is a tedious work as for each of its releases there is only a limited range of available compiled packages for specific Node and OS versions. Once one of those got too new or too old, better-sqlite3 must be compiled from source, which is even trickier job.

Describe the solution you'd like
Revise if better-sqlite3 is necessary, i.e. if we need to use SQLite and SQL at all, or if a simple txt + search will do the trick as well.

Describe alternatives you've considered
Search for alternative SQL/SQLite libraries, which do not require compiled sources.

Additional context
Makes problems repeatedly. Last time in Liberecký kraj Geoportal (https://github.com/LESPROJEKT/lbc_geoportal/issues/29)

Since Node 22 there is a native node package SQLite: https://nodejs.org/api/sqlite.html
