Add grafana datasource provisioning and update workflow docs

- Configure grafana to use provisioned datasources instead of UI config
- Add prometheus datasource template managed by ansible
- Create minimal grafana.ini with custom provisioning path
- Move ansible_managed to group_vars (fixes deprecation warning)
- Add Remote Hosts and Git Workflow sections to CLAUDE.md
- Document feature branch workflow with tea CLI for PRs
