Aligning Playback State Across All Surfaces

The lock screen remote control, mini player, and Reels were each displaying different playback states for the same track. A single playback fact was being interpreted independently across multiple UI surfaces.

This work focused on structural alignment rather than new feature additions. Now Playing, the lock screen remote control, the mini player, and Reels were consolidated to reference a single source of truth. Handling paths were also revised to ensure the UI reflects accurate state when desynchronization occurs between the audio session and track loading. The spatial and reverb effector chain was repositioned within the same playback path, ensuring consistency between playback state and audio rendering.

These inconsistencies do not surface in feature specifications, but they directly degrade the reliability of the playback experience. When lock screen controls reflect immediately in the mini player and playback continuity is maintained through Reels transitions, the playback layer operates as a stable foundation for the user experience.
