Allow editing collaborator roles & permissions after they are added

Is your feature request related to a problem? Please describe.

Right now, once a collaborator is added to a project, their role and permissions cannot be changed. If you assign the wrong role by mistake or if responsibilities shift later, the only workaround is to remove and re-add the collaborator. This is disruptive and makes managing project access more difficult.

Tell us about your idea - describe the solution you'd like.

I’d like to have the ability to update a collaborator’s role directly from the project settings. For example, an “Edit” option in the collaborator list where an Admin can change a user from Admin → Viewer → Editor without needing to remove and re-invite them.

Additional context

The last time I faced this issue was when a collaborator needed Admin rights during setup but only needed Viewer access later. I had to remove and re-add them, which was inconvenient. This happens often whenever team responsibilities change. Being able to update roles directly would save time, reduce errors, and make collaboration smoother.

Start at the project settings collaborator list and trace the existing add, remove, role, and permission flows. Identify where Admin users are authorized to manage collaborators and how role changes are represented. Done means an Admin can edit an existing collaborator’s role without removing or re-inviting them, with the resulting permissions applied correctly.
