fix: correct database type handling and SQLite configuration

Critical fixes for PostgreSQL, SQLite, and CockroachDB:
- Changed Postgres constant from 'psql' to 'postgres' (kept 'psql' as alias)
- Fixed SQLite config: 'host' -> 'database' in test workflow
- Updated getDriver() and buildConnectionString() to handle both 'postgres' and 'psql'
- Ensures proper database connections and table creation

This fixes the 'relation does not exist' errors by ensuring:
1. PostgreSQL/CockroachDB use correct connection strings
2. SQLite writes to correct database file
