Fix Pangolin config: use YAML format with required fields

Pangolin requires config/config.yml (YAML, not TOML) with specific required fields:
- gerbil.start_port, gerbil.base_endpoint
- app.dashboard_url, app.log_level
- domains.domain1.base_domain
- server.secret, server.cors.origins
- flags (signup, verification)
- database.path
- oidc configuration
