Fixes HA mobile app 403 when embedding Grafana dashboards - the webview
blocks third-party cookies needed by Authentik forward auth. Grafana
already has anonymous Viewer access enabled, so forward auth is not
needed. Also adds grafana_admin_password variable and explicit resource
limits to prevent ResourceQuota issues during rolling updates.
Add MySQL datasource and 15-panel dashboard for DNS analytics:
queries over time, response codes, top domains/clients, response
times, blocked/NxDomain domains. Enable Grafana dashboard sidecar
for auto-provisioning dashboards from ConfigMaps.
- Remove nginx-specific ingress variables (use_proxy_protocol, proxy_timeout, additional_configuration_snippet)
- Update ingress annotations to use Traefik middleware CRDs
- Delete nginx-ingress module (replaced by traefik)
- Add new traefik middleware.tf for shared middleware definitions
- Update service modules to work with new ingress_factory interface
