By keying the connections by the transport's resolved auth flow. This is important because connecting to the same SFU twice with the same participant ID will cause a 'duplicate participant ID' error that stops one of the connections.
This removes the notion of an auth flow fallback for now. We will no longer try the CS API when authenticating with transports that include both a `url` and `livekit_service_url`.

We already had text-overflow: ellipsis set on the title and subtitle elements of the app bar, but due to an annoying quirk of place-items: center, this had no effect. place-items: center stretch seems to give the text elements the right size constraints.
Port of edf1feae from johannes/rtc-remote-publish onto the SDK split,
where
the MatrixRTC logic lives in sdk/ rather than src/state/CallViewModel/.
Where the original lands:
- getLocalTransport's remote fallback: the LiveKit backend's new
findRemotePublishTransport (sdk/src/media-backend/livekit/
RemotePublishTransport.ts), which tries the candidates from the
js-sdk's
getRemoteLivekitPublishCandidates oldest first and keeps the first
whose
homeserver issues a token with the publish grant.
discoverLocalTransport
asks the backend for it after the host's fallback, with a snapshot of
the
session's memberships from RTCParticipation, and throws
MatrixRTCTransportMissingError where that finds nothing too. Transport
discovery stays backend neutral: the MSC4195 token check is the
backend's.
- LocalMember's "no delegation on a remote SFU" and the custom
transport's
server_name: LivekitBackend.prepareLocalTransport locates the
transport on
the homeserver it names (serverNameOfTransport) and skips the
delegation
probe where that is not our own.
- SessionBehaviors' membership.getTransportServerName: the same helper
in
LivekitBackend.mediaFor.
- decodeSFUJWTPayload, SFUJWTPayload.video.canPublish and the exported
isCsApiUnavailable: sdk/src/media-backend/livekit/auth/.
- DeveloperSettingsTab, the widget capabilities, the locale string and
the
js-sdk pin (9405287c, 44.0.0): applied as is. The error boundary
snapshots follow the string.
Tests: the LocalTransport cases go to RemotePublishTransport.test.ts and
LocalTransport.test.ts, the LocalMember remote case and the
SessionBehaviors
server-name case to LivekitBackend.test.ts, plus the memberships
snapshot in
RTCParticipation.test.ts.

The SDK MediaView renders a plain video element, so LiveKit's
data-lk-source attribute is gone. Expose data-source from the SDK track
and point the screen-share spec at it.
The SDK replaced `src/livekit` and the remote-member modules before that PR
landed on `main`, so its `src/livekit/auth/*` and `remoteMembers/ConnectionMap.ts`
have no consumer here: the same code lives under `sdk/src/media-backend/livekit`.
The imports of them that `main` added to the view model, the developer
settings tab and the test utils go with them.
The bumped js-sdk reports the legacy identity as rtcBackendIdentity for every membership, so a device that rejoins after an improper leave, which has two memberships until the stale one expires, produced two tiles with the same key and crashed the call view. The membership id tells them apart; the audio renderer keys by it too.
The developer setting that overrode the LiveKit service URL becomes a
JSON transport, so that a `url`-only or combined transport can be tested
against a homeserver that does not advertise one yet. The settings modal
shows each LiveKit room's role instead of a never-populated isLocal flag.
Folds "Avoid null in transport dev setting" from the same PR. The setting feeds the SDK's transport option; the config fallback becomes a transport the host builds.

A transport may soon carry a LiveKit SFU `url` instead of, or as well as,
a `livekit_service_url`, so a service URL alone no longer identifies it.
Pass the whole transport to the tiles' debug stats and print it as JSON in
log lines instead of picking out the service URL.
Element Call's media view models carry the member's raw transport from the SDK's TransportMetadata to the tiles.
A member authenticated through the legacy JWT endpoint publishes under a
`user:device` identity, while one authenticated through the default
endpoint publishes under a hashed identity. Both are listed in the
membership's backend identities, so match against the whole list rather
than only the primary one.
Element Call's test membership mock, matching the SDK's RTCMember.
