fix: Skip FTS5 validation for sql.js databases in Docker

Browse Source 
Resolves Docker test failures where sql.js databases (which don't
support FTS5) were failing validation checks. The validateDatabaseHealth()
method now checks FTS5 support before attempting FTS5 table queries.

Changes:
- Check db.checkFTS5Support() before FTS5 table validation
- Log warning for sql.js databases instead of failing
- Allows Docker containers using sql.js to start successfully

Fixes: Docker entrypoint integration tests
