Root causes:
- tia_admin_session is httpOnly so document.cookie could never read it → all
client-side cookie checks always failed and redirected before any data fetched
- Sub-pages used localStorage.getItem("admin_token") which was never stored,
and passed Authorization: Bearer null headers the server ignores
Fixes:
- FamilyProvider: use usePathname() hook instead of window.location.pathname
- admin/layout.tsx: rewrite as server component using verifyAdminSession()
(new lib/admin-auth.ts helper that uses next/headers cookies()) → server-side
redirect to /admin-login if session invalid; extract sidebar to AdminSidebar.tsx
- admin/page.tsx: remove broken document.cookie guard (layout handles auth now)
- admin-login/page.tsx: replace document.cookie check with GET /api/admin/auth call
- All 7 admin sub-pages: remove localStorage guard, remove Authorization: Bearer
headers, add credentials: include to every fetch call
