Add Role Assignment with Standardized Dropdown

[awesominat]

Assign roles to users:

Via drop-down on /admin/roleassignment, admins should be able to give users a new role (VP Infra, Web Deb, etc).

The different roles should be grabbed from Firestore (either by mocking it or using Firestore). The idea for it being a dropdown is to ensure uniformity and help prevent duplicate roles.

There should also be a way to add new roles, that also interacts with Firestore.

UI here isn't too relevant as this is mainly for site maintainers.

Description
We need a system where users can have different roles assigned for different years, ensuring accurate historical tracking of contributions. For example, a user might have been a "Member" in 2023 and a "Team Lead" in 2024. Roles should be selected from a standardized dropdown list, and only VPs can add new roles to the system.

Each user will have a yearList field in the schema that maps years to the assigned roles as yearList[year: [roles]].

User Story
As an admin (specifically a VP), I want to:

1. Assign roles to users for specific years using a standardized dropdown list.
2. Allow users to have different roles in different years, tracked via a yearList field.
3. Ensure only VPs can add new roles to maintain consistency across the system.

Acceptance Criteria

1. Yearly Role Assignments

   • Introduce a yearList field in the user schema that maps years to roles as yearList[2024: [roleList]].
   • Allow multiple roles for a single user within a given year.

2. Standardized Roles

   • Implement a dropdown menu containing a predefined list of roles (e.g., “Member,” “Team Lead,” “VP,” etc.).
   • Prevent manual entry of roles unless the user is a VP.

3. Add New Role Button

   • Include an “Add New Role” button, visible only to VPs, for creating new roles.
   • Newly created roles should immediately be available in the dropdown.

4. UI/UX

   • Allow admins to view and manage roles per year for each user.
   • Provide clear labels and guidance (e.g., “Assign Roles for 2024” or “Add Role to Year”).

5. Testing

   • Unit Tests: Confirm that yearly role assignments, dropdown functionality, and new role creation work as expected.
   • Integration Tests: Verify that only VPs can create new roles and that they appear properly in the dropdown.
   • Manual QA: Check the UI for correctness when assigning roles for multiple years to a single user.

Additional Notes

• Ensure that roles are validated for duplicates or near-duplicates to prevent confusion.
• Historical role assignments must not be editable by unauthorized roles or users.
• Future extensions might include filtering or sorting users based on their yearly roles.
