release: 3.40.1 — filter uses per-spec service names

Drop the invented "SMS-related" / "CB-related" filter categories: those
files are service-declared and are already reached through their
per-service options (per-spec service names).  Bump VERSION/pyproject/
PWA header to 3.40.1 and the SW cache to simple-v486.
