As an administrator i want to be able to edit group information

Administrators should be able to edit specific group information for a specific program through the admins page. This should be available in the programs tab. Select a program from the dropdown, then select the group from another dropdown and click a 'more info' button to redirect to the page. Here they can edit the info the same as a coordinator.

**Tasks**

Frontend
- [ ] Admin page
- add a group admin page and link it in the base admin page #3
- add a dropdown that list all programs (fetched from backend)
- when a program is selected, list all groups within the programs and display them in a table
- clicking on a group opens a modal with the group's full description
- add an edit button that turns on edit mode with a save or cancel button

Backend
- [ ] List groups endpoint
- GET request, given a program id, list all groups under that program, sorted by latest date first
- create 2 distinct permission (`view own group` and `view all groups` - or similar)
- base on which permission the user has, change the response
- if `view own group`, only return the group that the user is a part of
- if `view all groups`, return all groups under the program
- give `view own group` to coordinators and `view all groups` to admins
- [ ] List programs endpoint
- GET request, return all programs
- use a similar 2 permissions as above
- coordinators should only see programs that they are a part of
- administrators should see all programs

Start with the admins page and its programs tab, then trace the existing coordinator group-editing flow. Map the list-programs and list-groups endpoints and their permission behavior; the work is done when administrators can select programs and groups, view and edit group information, while coordinator and administrator visibility rules are enforced.
