feat(stores): retire events_loc — Svelte 4 persisted store fully replaced

events_loc has been completely removed after migrating all consumers:

- EVENTS_MODULE_TITLE constant replaces $events_loc.title (was always
  the static default 'OSIT\'s Æ Events', never written dynamically)
- events/+layout.svelte: qry__* writes moved to events_sess; stale-deploy
  ver check block removed (store_versions.ts handles this already)
- 3 stale pres_mgmt stragglers fixed: device_obj_li, location_page_menu,
  event_reports_page_menu now use pres_mgmt_loc.current directly
- testing/+page.svelte: missed launcher ref fixed (launcher_loc.current)
- events_loc export, events_local_data_struct, persisted import, and
  AE_EVENTS_LOC_VERSION import all removed from ae_events_stores.ts
- events_loc import cleaned from all consumer files

events_sess (in-memory writable) stays in ae_events_stores.ts unchanged.
store_versions.ts keeps its _check_and_wipe('ae_events_loc') entry to
clean lingering old data from users' browsers.
