fix(restore): preserve safe read context through nested lookups

Browse Source 
Carry restore context through POST status reads, metadata copy routing, null-version Object Lock checks and multipart completion. A failed read must preserve the target and must not enqueue its remote object for garbage collection. Cover initial/status POST failures and metadata loss during single and multipart rehydration on real disks.
