Live sync connections recognize a sync-unavailable outcome, handled like other skip reasons for backoff.

Live/container sync connections now recognize a sync_unavailable outcome, meaning the live channel is not available to the session right now. It's handled the same way as the existing boot_failed and ws_open_error skip reasons for retry/backoff bookkeeping.
