menu_launcher_controls: handle_cache_cleanup now removes both ae_events_loc
and ae_loc from localStorage, giving a true clean slate on reload.
e_app_help_tech: Clear & Reload button no longer silently re-saves ae_loc
after clearing — if edit mode wipes localStorage, ae_loc goes with it.
Updated confirm message and title tooltip to say "you will be signed out"
instead of the previous misleading "sign-in will be preserved."
