fix(calls): a finished call no longer rings again after a reload (#312)
After a reload/restart within a ring's lifetime, the catch-up sync replays
the ring together with the caller's hang-up and our own decline, and the
MatrixRTC session can keep the stale join. The client rang again for up to
90 s and showed "1 Live" (call screen instead of chat) for minutes.

- Before ringing, check the room STATE (utils/callRing.ts, unit-tested):
  no ring if we already declined that ring or are in the call; if the
  caller has no active membership yet, re-check after 4 s (a real call's
  membership can land just after its ring) and ring only if they joined.
- The "caller gone" dismissal also consults room state, not only the
  possibly stale session.
- When sync becomes live (startup or reconnect), recompute every active
  RTC session from the current state, clearing a stale "Live".

Verified headless (Bob's membership + ring in an invite-only room):
live ring rings; hang-up stops it; reload within the window: before
rang again + "1 Live", now no ring and no "Live"; a ring that arrives
just before the membership still rings.

Fixes #312
