xarmian 3e8bf36f3d feat(collab): count failed op-log appends (TASK-3574) (#2051) ...

pad_collab_append_failures_total counts each batch of sync frames whose
op-log append failed. The frames are still broadcast, so if the
originating tab closes before its catch-up, a later SyncStep2 can be the
only stored copy of the edit, and the item reads clean. The lead ruled
this counter the trigger for the SyncStep2 coverage check: any nonzero
week where that case could have occurred means build it.

Wired as an optional AppendFailureObserver on the TASK-3501 observer,
like OverflowObserver; the Room calls onAppendFail, set by the manager.
