The dashboard polls /api/analytics/usage and /api/analytics/models every
few seconds. When state.db is malformed the read raised straight through
the handler, so uvicorn logged a full traceback at ERROR on every poll —
one fleet host wrote ~520K identical journal entries in 24 h.
Wrap both analytics handlers in `corrupt_store_as_status`: a corrupt-image
sqlite3.DatabaseError (is_malformed_db_error) becomes a 503 with an
explicit `state_db_corrupt` payload pointing at `hermes doctor`, and the
warning is gated per store path via `{path: monotonic}` (>=300 s), then
debug. Busy/locked and every other error propagate unchanged, and the file
is never renamed or quarantined from the dashboard — repair stays with
`hermes doctor` / `hermes sessions repair`. `_session_db_path_for_profile`
is split out of `_open_session_db_for_profile` so the router can name the
store without opening it.
