[feature] When creating a Charter, show only groups where the current user is an admin in the dropdown #635
Description
Description
Currently, when creating a Charter, a user can select any group they are a member of.
However, after filling in the Charter and clicking “Save”, a generic error message appears: “Failed to create Charter.”
This happens because only group administrators are allowed to create and edit Charters.
The user learns about this restriction only at the very end of the flow and only from the API response
Proposed solution
To avoid this issue, the dropdown list of groups should include only the groups where the current user is an administrator
As a simpler alternative, a more specific and user-friendly error message can be shown when Charter creation fails due to partial permissions
