/**
 * `APP_BLOCK` handler test.
 *
 * Closes the gap from `docs/audits/lifeops-2026-05-09/03-coverage-gap-matrix.md`
 * line 438: the app-block handler had no executable test.
 *
 * Covers the three subactions (`block`, `unblock`, `status`) by mocking the
 * `app-blocker/engine.ts` surface — the single side-effect path the handler
 * dispatches into. The planner / arg-resolver path is bypassed by passing
 * parameters explicitly through `options.parameters`, so this is a true
 * handler-level integration: arg resolution → access gate → engine dispatch →
 * ActionResult shape.
 *
 * Owner-only access is exercised via `entityId === agentId` so the
 * `getAppBlockerAccess` helper takes the isAgentSelf shortcut.
