Two lifecycle holes Codex found in the new VPN management:
1. Delete removed the row before the hub knew. If the removal job was delayed
or failed, SyncVpnPeers saw a peer it did not recognise and adopted it back
as a live access — silently restoring what an operator had just revoked, and
with no row left to revoke it again. Deletion is now a soft-delete
tombstone: the row survives until the hub confirms the peer is gone, the
sync retries the removal instead of adopting, and the tombstone is purged
only once the peer is really absent. It also keeps the key and the tunnel
address reserved meanwhile, so neither is handed out twice.
2. ApplyVpnPeer applied the state captured at dispatch. A retried block job
could therefore undo a later unblock, and nothing would repair it — the sync
only observes state, it never re-applies intent. The job now resolves the
current desired state from the row and treats its payload as a fallback for
the case where the row is already gone.
