/**
 * RBAC view-level HIDING: operators/viewers must not SEE the controls they would be
 * 403'd from (the server-side abort_unless guards are proven in the Rbac*GateTest
 * suites). This only asserts the `@can(...)` wrappers render/omit the button markup —
 * a light UX check across a few representative surfaces, one per ability family:
 *  - Servers\Index  add-server trigger  → manage-fleet (admin sees, viewer does not);
 *  - Services\Index start/stop/restart  → operate      (operator sees, viewer does not);
 *  - the sidebar WireGuard nav item     → manage-network(admin sees, viewer does not).
 * Every SSH read is mocked — no real host is ever touched.
