fix(pangolin): Update controller configuration for deployment

- Use specific image version 0.1.0-alpha.1 instead of :latest
- Fix API endpoint port from 3001 to 3000 (correct Pangolin service port)
- Add CONFIG_ALLOW_INSECURE_HTTP for internal cluster HTTP communication
- Fix security context with numeric UIDs (65532) to avoid runAsNonRoot error
- Add required RBAC permissions for CRD and IngressClass discovery

Controller now successfully starts and acquires leader lease.
Next step: Configure API authentication (CONFIG_AUTH_HEADER) for
controller to access Pangolin API endpoint.
