TRIGGER_THIRD_PARTY_UPLOAD should be use only on specific cases

in !2821 (diffs) TRIGGER_THIRD_PARTY_UPLOAD is triggered on with_playable_uploads. But this will potentially trigger hundreds of download since sometimes it's use on the whole db...

We need to focus on context that have a limited amount of result : ~~- [ ] Radios : in RadioViewSet.tracks -> radio tracks are queried one by one, if we change this they will be triggered by a limited batch number ~~ edit : too much triggers

• Playlists : in PlaylistViewSet.tracks what if the playlist has 1000 tracks in it ?
• Limit the trigger to specific user ?
• Add a button in the track popover play button to trigger the hook
