Pull Request Overview

This PR enables supervisors to manage supervisee relationships directly from student profile pages by fetching pending requests and providing UI actions to add, accept, or dismiss students.

• Introduces a getSupervisionRequests action in the supervisor store to load pending supervision requests.
• Refactors matching and profile pages to use the store, adds buttons and modals for accepting, dismissing, or adding students as supervisees.
• Updates localization files and README to document new workflows and environment setup.

Frontend/pages/profiles/[id].vue:71

• The supervisee management buttons are rendered based only on the profile user's role (isStudent), but you also need to ensure the current user is a supervisor (currentUser?.role === UserRoles.SUPERVISOR) to prevent other roles (e.g., admins) from seeing these actions.

Frontend/pages/profiles/[id].vue:290

• [nitpick] The function name manageAddAsSupervisee is ambiguous when compared to addStudentAsSupervisee. Consider renaming it to something more descriptive like openAddSuperviseeModal to clearly convey its purpose.

const manageAddAsSupervisee = () => {

Frontend/README.md:6

• There's a typo here: "framwork" should be "framework". Also consider reviewing the rest of the README for typos like "I8ln", "managment", "compataibile", and "applicaiton".

## Tech stack

It all works nice! Just one small thing: When I am already supervising a student, then the button is still shown. It does not show the error from the backend, but that would be a nice to have. Bernhard also just implemented an endpoint to retrieve accepted requests from a user, if you want to do it that way --> #202

If you want you can already merge it like this, or add the above thing first and then merge. I will approve anyways :)
Just make sure to update the branch as I fixed one small thing
