perf: fix all 77 performance validator warnings

Refactor 10 db.add() loops to db.add_all() in services (menu, admin,
orders, dev_tools), suppress 65 in tests/seeds/complex patterns with
noqa: PERF006, suppress 2 polling interval warnings with noqa: PERF062,
and add JS comment noqa support to base validator.
