feat(hub): v0.57.0 reinstall-of-existing-customer arc — claim/offsite/escrow continuity

F2 claim re-issue on clean-slate re-enroll (ReissueForReenroll, host-enroll mint path,
single-bump, reset code; hub never stores the password so fork B). F3 offsite re-issue on
re-enroll (ReissueOffsiteForCustomer, same machinery as the manual button). 2.3 escrow honesty
(red-proofed): re-issuing offsite marks the escrow stale (MarkEscrowStale), withholds the
mismatched restic hash from auto-confirm, DR checklist shows stale not done. Events:
claim_reissued_reenroll / offsite_reissued / escrow_stale.

Controller + scripts unchanged (source contradicted both premises): the controller reads escrow
prereqs live from the agent; the installer can't know the descriptor-provisioned storage id. F4
root fix is agent-side -> ROADMAP R-22; demo unblocked live (Part 0 ACL grant). VALIDATION doc
F2 erratum + F3/F4 dispositions. Green gate + Scenario-C red-proof pass.

All of it landed cleanly — `notify/`+`claim/engine.go` in `6b40eb8` (v0.50.0), `store.go` in `a1d0450` (v0.54.0), plus follow-up `e205a2d`; v0.55.0 shipped. Working tree is clean, no stashes.
