Rename `values_helmChart__passive.yaml` to
`values_helmChart__backup.yaml` and `values_helmChart.yaml` to
`values_helmChart__primary.yaml`.
These changes improve file clarity by explicitly indicating
the purpose of each values file. The primary configuration
is now more identifiable with its new name, while the backup
file is clearly designated, reducing confusion for future
updates and maintenance. There are no breaking changes
associated with these renames.
