fix(call-to-play): expire elapsed calls clearly

Deadline completion previously shared the green Ready presentation with a full
roster and remained visible forever. An abandoned call therefore looked ready
to launch and required its creator to return and cancel it.

Give elapsed calls a distinct Time's up state and a five-minute grace period in
which the creator can start or extend them. After that, both the reducer and
peer store remove the call as a unit. Filled calls remain ready until their
deadline, and active calls continue to retain complete history for late joiners.

Test Plan:
- `just fmt` -- passed
- `just clippy` -- passed
- `just test` -- passed, 147 peer tests
- `just frontend-test` -- passed, 22 tests
- `just build` -- passed
- `git diff --cached --check` -- passed
