db_events.file.clear() after every upload was nuking the entire Dexie file
table. Every liveQuery watching any file list (Launcher, other locations,
sessions, presenters) would immediately show 0 results. Only the uploaded-to
object's files were reloaded; all others remained empty until their own
background syncs fired — intermittent disappearance that depended on timing.
Fix: targeted load_ae_obj_li__event_file for only the current link_to_id,
which uses the SWR pattern (returns cache + background refresh that includes
the newly created file). Other objects' file caches are untouched.
