Removed 55 unused imports across 26 router files. Most were `db` imports
left over after the db.close() removal in the previous commit, plus
additional stale imports (scipy.stats, chunked, copy, base64, Html2Image,
pandas.DataFrame, pydantic.validator, etc.) that were already unused.

Add db_session_middleware to main.py that opens the connection at the
start of each request and closes it in a try/finally block, ensuring
connections are always returned even on uncaught exceptions.
Remove all individual db.close() calls from 30 router files in
app/routers_v2/ — the middleware now handles all code paths.

- Add explicit ORDER BY id to all queries for consistent results across SQLite and PostgreSQL
- PostgreSQL does not guarantee row order without ORDER BY, unlike SQLite
- Skip table creation when DATABASE_TYPE=postgresql (production tables already exist)
- Fix datetime handling in notifications (PostgreSQL native datetime vs SQLite timestamp)
- Fix grouped query count() calls that don't work in PostgreSQL
- Update .gitignore to include storage/templates/ directory
This completes the PostgreSQL migration compatibility layer while maintaining
backwards compatibility with SQLite for local development.
