Replace 71 broad `except Exception` blocks in 19 router files with the
specific `peewee.DoesNotExist` exception. GET endpoints that call
`Model.get_by_id()` now only catch the expected DoesNotExist error,
allowing real DB failures (connection errors, etc.) to propagate as
500s rather than being masked as 404s.

Replace all logging.warning(f'Bad Token: {token}') calls with
logging.warning('Bad Token: [REDACTED]') across 30 router files.
Full bearer tokens were being written to log files on auth failures.

Moved logging.basicConfig() to app/main.py as the single source of truth.
Removed duplicate (no-op) calls from app/db_engine.py, app/dependencies.py,
and all 30 router files in app/routers_v2/. Removed the now-unused LOG_DATA
dict and date/log_level locals from dependencies.py and db_engine.py.

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.
