Added Kanidm server configuration to serve as central identity provider for
all services. Configuration includes:
- Server on auth.baduhai.dev with HTTPS
- LDAP support on port 636 for legacy integrations
- Nginx reverse proxy with SSL termination
- Added to shared services for DNS resolution
Kanidm will provide OAuth2/OIDC authentication for Nextcloud, Vaultwarden,
Forgejo, and other services.
Migrated forgejo service and configuration to trantor. Added nginx reverse
proxy support on trantor with ACME configuration for SSL certificates.
Fixed vaultwarden domain in shared services from vault.baduhai.dev to
pass.baduhai.dev to match actual nginx configuration.
Created centralized service definitions in shared/services.nix to store
service metadata (domains, IPs, ports) that need to be accessible across
multiple hosts. This replaces the per-service split DNS module approach
with a single source of truth.
Services are now exported through utils.nix for easy access in host configs.
