Refine TV player inline playlist flow

Move the TV player queue into a simplified bottom inline playlist row and keep the existing seek bar -> controls -> playlist navigation hierarchy.

Focus playlist entry on the current queue item, keep focus pinned on the row at the horizontal edges, and return to the controls row on Up/Back.

Add compose coverage for playlist expansion, current-item focus, fallback focus, and row edge navigation.
