[registry] Add application labels and update filtering mechanism
- Add three application metadata labels to HelmRelease:
  - apps.cozystack.io/application.kind
  - apps.cozystack.io/application.group
  - apps.cozystack.io/application.name

- Replace shouldIncludeHelmRelease filtering with label-based filtering
  in Get, List, and Update methods

- Always add kind and group label requirements in List for precise filtering

- Update CozystackResourceDefinitionController to watch only HelmReleases
  with cozystack.io/ui=true label

- Update LineageControllerWebhook to extract metadata directly from
  HelmRelease labels instead of using mapping configuration

- Add functionality to update HelmRelease chart from CozystackResourceDefinition
  using label selectors
