feat: stop a transient Graph failure on a folder's first backfill page from marking that folder's backfill permanently complete: msgraph.HandleError mapped 404, every 5xx and any unrecognised status onto the same ErrMailServerUnreachable, so graphBackfill's "the tenant does not have this folder" skip fired on a 503 as well and wrote the folder off in a cursor that is persisted through SYNC_STATE and handed back on every later load, silently costing a customer who connected a mailbox during a Graph incident their archive history; 404 now carries its own RESOURCE_NOT_FOUND code, the skip keys on that alone, a genuine unreachable server ends the pass with the folder's cursor held so the next one retries it, and the Gmail and IMAP imports get the same regression shape pinned by tests
