Justin Gu 0e74752701 fix(web): validate market/category input — support lowercase, reject invalid with 400 ...

Root cause: _market_from_str/_market/_category in routers used bare
MarketEnum[key]/Market[key] without .upper() or try/except, so
lowercase or invalid values (sz, ZZZ) threw uncaught KeyError → 500.

Fix: extract shared convert.py with market_from_str/category_from_str
that do .upper() + ValueError on invalid input.  All 4 routers updated.
4 regression tests added for case-insensitive and invalid input.
