fix: keep DB credentials populated and skip fulltext indexes on adapters that lack support

Two fixes for the SQLite test wiring:

1. .env had emptied _APP_DB_USER/_APP_DB_PASS/_APP_DB_ROOT_PASS, but the
   mongodb/mariadb/postgresql containers still consume those during init
   regardless of which adapter Appwrite uses. Empty values left the
   side-running mongodb (needed for documentsdb) refusing to start, which
   blocked docker compose up --wait for every CI matrix row, including
   MongoDB. Restoring the original test credentials.
2. Bootstrap was unconditionally creating fulltext indexes from collection
   configs. SQLite adapter explicitly returns false for
   getSupportForFulltextIndex(), so it threw on the first such index. Now
   the bootstrap consults the adapter and skips fulltext indexes when not
   supported.
