fix(ui): display valuesobject if set (#14257) (#14755)

* fix: display valuesobject if set

With #11538 we now have the ability to set helm values as an object
instead of a string, but we also need to be able to correctly display
it in the UI if it is set.



* fix: set valuesobject on save

If `valuesObject` is present, set it to the value of
`input.spec.source.helm.values` on save, as an unmarshaled json string.



* fix: set `helm.values` to empty string on save

If `valuesObject` exists, set `input.spec.source.helm.values` to an
empty string once `valuesObject` has been unmarshalled from the
values input. This is to prevent unnecessary duplication of the values.



* chore: eslint



* chore: eslint



* fix: deep clone app

This is so that we can conditionally set `source.helm.values` without
inadvertently affecting other parts of the app. Only when the edit
button is pressed do we toggle `source.helm.values`.



* chore: eslint
