fix(events): event location file load on mount + launcher pruning scope fix + remove legacy launcher btn

- Location page now calls load_ae_obj_li__event_file on mount so files
  appear immediately without requiring a manual Refresh press.
- _load_event_location_sub_data (Launcher 60s sync) now uses hidden='all'
  with default limit (100) instead of hidden='not_hidden'/limit=25, which
  was pruning valid Dexie records when Pres Mgmt and Launcher were both
  open on the same location simultaneously.
- Removed the legacy launcher button (Send icon, /event/ path) from the
  Locations list; removed unused Send icon import.
