hub: operator actions for a box (D1, R-314/R-279/R-177, decision 185)

Host page "Operator Actions" card: run off-site backup now, run a check now
(fixed job list), stop / extend (1-30 days) a deletion countdown. POST
/hosts/{id}/operator-action validates against the CLOSED list before
storing (unknown -> 400, no row), stores operator_actions(id, customer_id,
action, arg, requested_at, requested_by, done_at, outcome, message), logs
who pressed (channel + address) and bumps the box's intent. The report ACK
lists pending rows as operator_actions until the box's
operator_action_results closes them (matched on id AND reporting
customer); each closed row becomes a hub-minted operator_action event
(stored, never dispatched). Unanswered after 24 h: expired. A customer
RESET cancels pending rows. Wire gate: new root + field-by-field mirror
(controller report.OperatorAction) — needs the controller commit first.
