feat(calls): change noise suppression mid-call without rejoining

Changing Noise suppression (off / browser-native / ML), the ML model, the
gate or "stack browser NS" in Settings now applies to the call you're in.
useCallDenoise sends the fork's io.lotus.set_denoise whenever those
settings change; CallControl join-gates it like set_quality and re-sends
it after an EC reconnect (the remounted fork handler starts again from
the join URL). The "requires rejoining the call" note is replaced.

Bumps Element Call to 0.28.0-lotus.4, which adds io.lotus.set_denoise and
fixes mic re-captures silently keeping the old noiseSuppression (the mic
level meter's clone held the old track open), the meter following the
old device after a mic switch, and voiceIsolation staying on in off/ML
modes (element-call#66).
