Metrics are served on METRICS_PORT (default 2112, "off" to disable), never on
the public port. Besides the Go runtime and process metrics this adds:
- http_requests_total and http_request_duration_seconds per route pattern,
from an Echo middleware.
- musicserver_songs_requested_total and musicserver_songs_played_total by
pick mode (random, low, classic). The mode is now stored with each queued
song (migration 000006, not released yet).
- Library size, sync duration, last successful sync, broken songs from the
last full sync, and the database connection pool.

The queue lived in memory and was shared by all clients, so a restart or a
finished sync cleared it. Every client now has its own queue in the new
queue and queue_song tables (added to the undeployed migration 000006).
The music endpoints return the queue ID in the X-Queue-Id header and expect
it back. A request without an ID, or with an ended one, starts a new queue.
/music/reset ends the queue and returns a new ID, and a sync ends all
running queues. Ended queues are kept as history.
The deprecated legacy routes without the /api/v1 prefix are removed.
