feat: keycloak integration and redeploy button

[shini4i]

This pull request incorporates the following changes:

• Adds a basic integration with Keycloak to the frontend (optional)
• Adds the OPEN IN ARGOCD UI button to simplify troubleshooting
• Adds the ROLLBACK TO THIS VERSION button to the page with task details visible only if the user is authenticated and a member of the provided privileged group.
• Hides "Status Details" on Deployed tasks as there is no reason to show an empty field

There are still some open questions about the logic behind this button, as we need to provide a token to the backend, usually supplied by the client. The user should not have it. We can't really reuse the token from Keycloak as the backend has no connection with it.

Currently, I've implemented the most straightforward approach. We ask the user to provide the token manually.

When merged, it will close #175

Although these changes do not break the backward compatibility, they are still pretty big. I would appreciate it if you guys could take a look. @bozerkins @rustamar @tomsozolins
