Restore credentials in appsettings per owner decision

The committed connection strings, EmailSettings and seed-admin password are
intentional configuration for this project, not a bug. docker-compose no
longer requires env vars; deployment works exactly as before. The seeder
stays config-driven (SeedAdmin block now committed), and env-var overrides
remain available if ever wanted. bug-fixes.md updated to reclassify #15/#16.
