reject_node only set approval_status, so an approved-then-rejected node kept
its dynsec login, its /upload key and /systems read access.
- reject_node: status -> rejected first (fail-closed), then
dynsec.delete_node_client, then delete node_keys. dynsec failure -> 502,
key kept, retry is idempotent. Re-approve mints a fresh key.
- upload.py: valid key alone is not enough; node must be approved (403),
uncached read so revocation bites immediately.
- dynsec.reconcile_all: deletes rejected nodes' logins on startup, healing
nodes rejected before this change or whose revoke failed.
- Reject confirm text says it revokes.
