test: Local Authorization Policy testing with SSH tunnel

- appsettings.Development.json: SSH tunnel to remote PostgreSQL (127.0.0.1:5432)
- Verified Authorization Policy registration in Program.cs
- Tested locally: All /Admin/* pages correctly redirect (302) to login
- Build: 0 errors, 7 warnings (pre-existing, unrelated to this fix)
