The endpoint iterated over `files.vl_basic` (a string, not parsed CSV),
causing it to loop over individual characters. The body contained only
`pass` with TODO comments and no running stats logic. Removed the
endpoint entirely along with the dead commented-out csv helper code.
The `BattingFiles` model is retained as it is still used by
`live_update_pitching`.

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.
