🔧(helm) offer a standalone dev environment

Offer a standalone dev environment or a dinum specific dev
environment with ProConnect authentication.

Needed to refactor the way secrets are managed in the project,
and also re-organize the Helm chart to make it totally standalone.

Particulary useful for external wanting to run the project.
Work done by @rouja.
