fix: remove Flux validation and fix YAML linting

- Remove Flux validation job (repo doesn't contain Flux resources)
- Fix trailing spaces in best-practices workflow
- Add missing newline at end of znc/statefulset.yaml

Flux validates Kustomization CRDs, not plain manifests. Since this
repo only contains the manifests deployed by Flux (not the Flux
resources themselves), the validation doesn't apply.
