Enhanced Events Launcher Location loading and instructions.

Implemented explicit 'enabled' and 'hidden' parameter support in the Event data layer ('load_ae_obj_id__event').

Updated the Events Launcher layout and background sync engine to proactively fetch all enabled locations (including hidden ones), ensuring the room select list is complete and stays updated.

Refined 'launcher_file_cont.svelte' to only display native-specific file opening instructions when 'app_mode' is 'native'.

Updated AGENT_TODO.md to reflect task completion and new priorities.
