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.

Echo compares allowed origins literally, so "https://*" and "http://*" never
matched a real origin and no CORS headers were sent. The allowed origins now
come from CORS_ALLOWED_ORIGINS (comma-separated, checked at startup). When it
is empty, only same-origin requests work, which is enough for the bundled
frontend.
Credentials are no longer allowed since the API uses Bearer tokens. Browsers
may now send Range and X-Queue-Id and read X-Queue-Id and Content-Range.
- Unit tests use an in-memory fake database (internal/testutil/fakedb),
temp folders and httptest; `go test ./...` needs no Docker or env vars
- Integration tests (build tag "integration") start PostgreSQL with
testcontainers: migrations step by step, SQL dumps (skipped if
missing) and a full sync against a real database
- Removed tests that only checked copies of the logic or had empty
bodies, the broken root integration_test.go, compose.test.yaml and
.env.test with hardcoded paths
- testMusic MP3s replaced with tiny placeholders (sync never decodes
audio), 194 MB -> 168 KB
