MAS-WP-0010 finished: email slave role, stub outside master, contract flows, SCP-8

- EmailMode slave role: master-issued case ids, events to the master,
  sends only on instruction or autonomous policy, transfers blocked or to
  a primed webhook, timeouts left to the master; principle 10 refusals
  reported back.
- conformance/flows.json (13 flows) + mas_modes.runner; mas test runs the
  mode corpus (172/172).
- SCP-8 / v0.2 section 7.1: !MODE requests a handoff defined by the mode
  contract. docs/reuse-surface.md.
- Deploy image copies mas_modes (ticket service imports its mailer).
