refactor: stabilize event file management and ID synchronization

- Updated 'process_ae_obj__event_file_props' to synchronize generic 'for_id' with specific object IDs (e.g., 'event_presenter_id').
- Standardized 'element_manage_event_file_li_direct.svelte' to use specific ID filtering.
- Fixed missing 'prevent_default' in 'ae_comp__hosted_files_clip_video.svelte'.
- Resolved miscellaneous type and syntax errors identified by svelte-check.
