feat: migrate to artifactapi 3+

What changed:
- Adds new v3 API and UI deployments (separate api-deployment.yaml, ui-deployment.yaml) alongside the existing monolithic artifactapi-deployment.yaml
- Adds CNPG PostgreSQL cluster + pooler to replace the standalone postgres deployment
- Adds new api-env configmap, new Vault secrets (postgres-credentials, environment), and a second VaultAuth (default1)
- Adds new services targeting the split api and ui selectors
- Adds HPAs for both new deployments
- Updates kustomization to include all new resources
