EPIC: Staff CRUD operations (multiple stories, some of which can be done in parallel)

[github-actions]

User Story

• As an admin
• I can perform Create, Read, Update, Delete operations on staff
• so that I can manage the staff's for that particular course without having to go through swagger

Discussion

The Staff Backend API for CRUD operations is already working and available on the swagger and controllers.

However, we don't yet have a frontend. We need a frontend, similar, probably to the one you build in team03

Acceptance Criteria

NOTE: it is strongly recommended to break this into multiple issues: for example, as team03 was broken into issues, and do separate PRs for each part. You could start by just creating a form and a table, and different team members could be assigned to do each of those.
