Two more frozen GET routes that return a static 200:
- GET /bmx/registry/v1/servicesAvailability (embedded availability registry JSON)
- GET /ced/soundtouch/mr4_22097fe2/index.xml (CED firmware-update config; a
present static file is 200, absent paths 404)
COVERAGE.md: correct the rows that were already covered by the first batch but
left marked as gaps (/v1/auth, /v1/scmudc, orion station, custom playback,
ding, bmx-icons), and record the two new routes. Remaining gaps are the ones
that need an upstream fixture (tunein episode), prior TTS state (media/tts), or
are quirky-status edges.
