ATEM: RESI AUDIO SILENT when input 16 has no audio for 30 s; log what the switcher has wrong

2026-10-25 the Resi AJA passed no Dante audio and the panel stayed green (DANTE only sees the card on the
network). atem_watch.js now asks the switcher for its Fairlight meters and reports a metered input
stuck at the floor (-100 dB); the ATEM key turns red in auto-fix's hours or while a deck records.
Differences (audio, camera, silence) are logged when they change, so a fault says what it was.
