Make yamllint more forgiving and exclude only k8s templates

- Remove extensive file exclusions, keep only k8s templates
- Increase line length limit to 400 chars (GitHub Actions friendly)
- Allow flexible colon spacing (max-spaces-after: -1)
- Disable document-start requirement

This provides linting value while handling infrastructure patterns.
