Give admin owner role to all projects is not complete - Part II

[judge-red]

What would you like to be added? / User Story:
#6754 (in 2.26.0) had the title "Give admin owner role to all projects". First of all, thank you, this has long been missed! This is a follow up feature request, i.e. Part II. I've only spent a few minutes with this feature yet, so maybe I'll have more to add later, but for now I noticed the following things.

Indeed, I can create a cluster in a project of which I'm not a member now, including using a preset only available in that project. However, the "Open Dashboard" and "Web Terminal" buttons are greyed out. imho these should be available to me (as an admin and cluster-admin of the cluster I created) as well.

Furthermore, I can now add myself as a member of the project, finally! But I still can't remove myself :( Okay, this one might not directly be related to the original feature that was implemented, as preventing to remove myself might be a separate protection. But please, I need to be able to remove myself after I added myself to a project. Edit: also, I still can't edit my own role.
