fix: remove _oem_blocked() from catalog search/part + expose autoMatchCompat

- catalog_bp.py: /search and /part/<id> no longer blocked by CATALOG_OEM_ENABLED
  These endpoints query the master parts DB and enrich with local stock;
  they should work in both local and OEM modes.
- inventory.js: expose autoMatchCompat and removeCompat to window for
  onclick handlers in dynamically generated HTML.
- Regenerated inventory.min.js
