test(binary): drain AwaitingInitialSync timer & fix stale comment

Addresses 2 review comments on PR #384:

- Codex P2: the fresh-pair test ended the socket immediately after the
  buffer assertion, leaving the 2s setTimeout in chats.ts:1522 alive.
  Its callback fired post-teardown and emitted "Cannot log after tests
  are done" via baileys-logger, making the suite noisy and trippable
  by --detectOpenHandles. Drain the timer with a 2.1s wait before
  cleanup; bump the per-test timeout to 10s to accommodate it.

- Copilot: the file header said "live messages are not held for up to
  4 seconds", but the chats.ts AwaitingInitialSync timeout is 2s.
  Replace the stale literal with "the initial-sync window" so the
  comment doesn't drift again when the timeout is tuned.

Skipped intentionally (per PR review):
- CodeRabbit Major (try/finally cleanup): diverges from the pattern
  used by the only sibling test (connection-deadlock.test.ts).
- CodeRabbit Nitpick (replace 50ms sleeps with deterministic waits):
  not flaky in practice; sibling test uses the same pattern.
