Ryan GausandClaude Opus 5.5 5a5a6132c7 Disable AV1 for Firefox clients before 157 (#4962) ...

Firefox 155 enabled AV1 for WebRTC by default, but Firefox 155/156
decode only the base spatial layer of an AV1 SVC stream. SVC is not
visible in SDP, so such a subscriber that negotiates AV1 is forwarded
the publisher's AV1 SVC stream instead of its backup codec, rendering
black whenever a higher layer is selected. Firefox 157 decodes the
higher layers correctly (client-sdk-js#2116), so it keeps AV1.

Removing AV1 from the subscriber's enabled codecs keeps it out of the
SFU's offers and answers, so the down track binds to the backup codec.
Firefox never publishes AV1 either, so it is disabled in both
directions, the same as Safari.

The Firefox for Android H.264 rule is switched to merge so it no longer
drops the AV1 rule for that browser.
