Fix redirect loop on session expiry and add missing nav links

- Add redirectGuestsTo in bootstrap/app.php so unauthenticated users
  always redirect to the full account login URL instead of a relative
  /login that would 404 on the admin subdomain or loop
- Create HandleInertiaRequests middleware to share auth.user, flash
  messages, and domain config to all Vue pages (was entirely missing)
- Add Profile nav link in AppLayout, "Customer View" link in AdminLayout
- Point logout to account subdomain where Fortify routes live
- Link AuthLayout logo back to marketing site
- Fix Marketing/Home links to use full account subdomain URLs
- Update RoleBasedAccessTest to match new redirect URL
