Subject: [PATCH] Fix contact sync fallback when channel 0 never arrives

On web BLE, contact sync is deferred until channel 0 arrives via
_handleChannelInfo. If channel 0 times out or channel sync completes
without it, _pendingInitialContactsSync stays true and contacts never
load. Add fallback in _cleanupChannelSync to trigger getContacts() if
the flag is still set when channel sync ends.
