The per-env approval policy was applier-supplied — a hand-crafted request
that omitted `project.environments` was ungated, and flipping a gate to
`confirm = false` in the same request un-gated it. Persist the policy
server-side and enforce against `persisted ∪ declared`.
- Migration 0067: `project_environments (project_id, env_name, confirm)`,
CASCADE on the project. Written declaratively (delete-then-insert) inside
`upsert_project_tx`, same tx as the project row + node claim.
- `ProjectRepository::get_environments_by_slug` (read side) +
`ApplyService::effective_env_policy` union the persisted policy with the
request's declared one (confirm if EITHER says so — monotonic).
- `env_gate_check` now evaluates the effective policy; the three handlers load
it before the gate. `plan.approvals_required` is the effective gated set, so
CI sees a persisted gate even when the manifest omits it.
- The union rule closes both bypasses: an omitted policy still trips a
persisted gate, and an ungating apply must itself pass the gate (the
declarative replace then takes effect next time) — TOCTOU-safe.
