When a session ID is sent to POST /api/memory/import but that session no
longer exists in the DB, the previous code raised HTTP 404. The import
endpoint only needs the session as an LLM-config source; the file being
imported has nothing to do with the session. A fallback to the utility
endpoint (already used when no session_id is supplied at all) is correct
and safe.
The extract endpoint is intentionally left alone — it reads the session's
message history and therefore genuinely requires a live session.
