feat: add is_disney column for reliable Disney/Non-Disney filtering

- Added is_disney INTEGER DEFAULT 0 column to assets table
- Backfilled 996 Disney assets based on D- customer prefix
- Server: is_disney in AssetCreate/AssetUpdate models, INSERT/UPDATE
- Server: disney_filter query param now uses is_disney column (no JOIN needed)
- import_cantaloupe.py: sets is_disney=1 when customer starts with D-
- import_machines.py: sets is_disney=1 when customer starts with D-
- disney_classify.py: sets is_disney=1 when classifying
- Frontend: new Location Type dropdown with Disney/Non-Disney toggle
  (replaces the __disney__/__non_disney__ park dropdown pseudo-options)
