Open Link gets a Load action that resolves one link and shows its video
details page, playlist or channel screen instead of only playing or
downloading it. Play and Download stay as shortcuts for video links.
Timed links start at their timestamp from the details page, the Show
Details link action opens the details page, and a short extraction cache
avoids re-extracting the same link for details and playback.
Playable files in the media source browser now honor tvOSVideoTapAction
on tvOS and thumbnailTapAction/textAreaTapAction on iOS/macOS, matching
other video lists. When openInfo navigates to VideoInfoView, playback
routes through QueueManager.playFromMediaBrowser so stream and caption
resolution keep working for Samba/WebDAV files.
