fix: Org admin can remove team members without being on team

[Dschoordsch]

Description

Fixes #11138
The mutation tried to always load the viewer team member which would fail if the org admin wasn't on the team.

Demo

I made a few UI changes to work with long names. I removed the name from the context menus

And modified the delete and promote modals to wrap the button

These are extreme cases, so I think it's good enough for now.

Testing scenarios

• as org admin remove a team member from a team you're not a member of

Final checklist

• I checked the code review guidelines
• I have added Metrics Representative as reviewer(s) if my PR invovles metrics/data/analytics related changes
• I have performed a self-review of my code, the same way I'd do it for any other team member
• I have tested all cases I listed in the testing scenarios and I haven't found any issues or regressions
• Whenever I took a non-obvious choice I added a comment explaining why I did it this way
• I added the label Skip Maintainer Review Indicating the PR only requires reviewer review and can be merged right after it's approved if the PR introduces only minor changes, does not contain any architectural changes or does not introduce any new patterns and I think one review is sufficient'
• PR title is human readable and could be used in changelog
