_call_is_substanceless's "type" veto reads ctx["incident_type"] at decision
time, but that value was never persisted per-scene — only the last-scene-wins
flat field, which #138's window-4 dump analysis couldn't tell apart from
cross-scene contamination without re-guessing from a live dump. Adds
incident_type/severity to _apply_and_log's per-scene write and to admin.py's
_scene_summary allowlist (the debug-dump reader has its own field allowlist,
separate from the write side — silently would not have surfaced otherwise).
Sandboxed pytest: 380 -> 381.
