☑️ Resolves

• Fix Aspect-ratio for video-tracks is not considered #8815
• Issue is actually in two parts:
  • 1 - 16:9 is constrained to 4:3 - was due to strict constraints, changed before. UI for local video might still be locked to 4:3 aspect ration, but full video is translate - there are other isues ope for that topic
  • 2 - constraints are not re-applied after source change / camera state change -> new video stream goes as-is - fixed with this PR
