feat: reconcile offline page movement atomically

Retain batch placement preconditions and identities through restart and reviewed
conflicts. Confirm publication only from complete multi-space revision evidence,
and refresh stale native metadata when changing page topology.

Validate eighteen native movement combinations and twelve offline branches with
retained cold captures, interrupted publication tests and stateful ASan runs.
