refactor: switch to cookie-based auth flow with JS interop fallback

Architecture shift:
- Primary: HTTP-only cookie authentication (server-side)
- Fallback: localStorage with JS interop for SPA

Changes:
1. CustomAuthenticationStateProvider:
   - Add IJSRuntime for direct localStorage access
   - Try JS interop first, fallback to LocalStorageService
   - Added detailed logging for auth debugging

2. Dashboard.razor:
   - Add @rendermode InteractiveWebAssembly (CLAUDE.md compliance)
   - Restore auth check with logging
   - Redirect to /login.html if not authenticated

3. Program.cs:
   - Reorder MapRazorComponents: WebAssembly first (default)
   - Add detailed logging to /api/auth/login cookie setup
   - Verify Set-Cookie headers are sent correctly

4. login.html:
   - Simplified to 2-second wait before redirect
   - localStorage as backup storage
   - Ready for cookie-based auth

Next steps:
- Verify Set-Cookie headers appear in responses
- Confirm cookie-based auth works end-to-end
- Test dashboard loads with cookie authentication
