for jellyfin 12.1
- jellytag: fix season menus and failed menu retries, and update the tag editor
- thumbnail previews: authenticated trickplay, trailer fallback and cleanup, with the original preview icons
- remote trailers: fix native controls, settings, playback speed, playback info and cleanup
- privacy mode: fix keyboard and shift sequences, and cover the updated screens and previews
- curator plugins: fix collections returning after deletion and wait for collection saves to finish
if overlapping menu requests leave jellytag's target uncertain, native menus still work; reload to restore tag actions.
curator updates still emit normal item update events, but no longer emit collection-specific add/remove events.
