/**
 * Integration tests for the dashboard router.
 *
 * Covers:
 *  - Both endpoints reject unauthenticated requests (global authGate).
 *  - GET /api/dashboard/configuration returns the documented shape and
 *    applies tier-correct `locked` flags for Community, Skipper, and
 *    Admiral personas (toggled via LicenseService spies).
 *  - GET /api/dashboard/stack-restarts clamps the `days` query parameter
 *    to [1, 30] and falls back to 7 for invalid inputs.
 *  - Neither endpoint leaks secret material (agent URLs, tokens) in the
 *    response payload.
