- backend/src/auth.js: extract caps from JWT (planner/settings), hasCap/requireCap
- backend/src/routes/config.js: gate categories + test-connection on requireCap('settings')
- frontend/src/types.ts: add caps[] to User, export can() helper
- frontend/src/App.tsx: gate /settings route on can(user, 'settings')
- frontend/src/components/Layout.tsx: gate nav item on can(user, 'settings')
