fix: Customizable HelmRepository.spec in umbrella kof chart

[denis-ryzhkov]

• We need optional HelmRepository.spec values like secretRef and certSecretRef.
• The hardcoded type: "default" should be customizable too.
• Deleted the unused kcm.kof.repo.spec too.
• Tests:
  • empty spec
  • non-empty spec

Pull request overview

Enables more flexible FluxCD HelmRepository configuration in the kof umbrella chart by allowing users to pass through optional HelmRepository.spec fields (e.g., secretRef, certSecretRef) and by making the VictoriaMetrics repo type configurable instead of hardcoded.

Changes:

• Add global.helmRepo.spec pass-through values in the umbrella chart values/docs.
• Refactor helmrepositories.yaml to render repo fields via value blocks and remove hardcoded VictoriaMetrics repo type.
• Simplify kof-mothership chart repo values/docs to reference an existing HelmRepository name only.
