Introduced `/music/{guildId}/play` and `/music/{guildId}/play/select/{searchId}` POST routes for initiating and selecting music playback via the REST API. Added `/music/{guildId}/pause` and `/music/{guildId}/resume` POST routes to control playback state. Updated the music system with `RestTrackLoadingHandler`, `PlayOutcome`, `PendingSearchResults`, and DTOs for OpenAPI integration. Enhanced `MusicManager` to support REST-driven play requests with robust error handling and improved track loading logic.
