fix(import): IgnoreQueryFilters so revive sees soft-deleted scenes; clear AE crash state

- AepImportService: the global Scene HasQueryFilter(DeletedAt==null) was hiding
  soft-deleted rows, so the revive never matched and the importer re-inserted →
  scenes_project_id_key violation. Add .IgnoreQueryFilters() to the load. (apply
  now revives + returns 200, verified.)
- node-agent: ClearAECrashState() deletes AE's SCRPriorState.json before each
  launch so the 'Crash Repair Options' dialog can't hang a headless scan/render.
