engine: expose sequence video dimensions in the timeline facade

Browse Source 
- oakengine_sequence_get_video_params (width/height/pixel aspect) with
  assertions for the default 1920x1080 square-pixel sequence and the
  invalid-handle path
- oak-cli now renders at the sequence's real dimensions instead of the
  hardcoded 1920x1080
