fix: web UI routines tab shows all routines regardless of creating channel (#391)

Routines created via Telegram (or any WASM channel) were invisible in the
web UI because the routines list endpoint filtered by GATEWAY_USER_ID,
which didn't match the Telegram user's ID stored on the routine.

Add list_all_routines() to the RoutineStore trait (both libSQL and
PostgreSQL backends) and use it in the web dashboard handlers so all
routines are visible regardless of which channel created them.
