User Story: As a user managing access, I want to have a search input field on the users table in both the access management and project access management pages, so that I can quickly find and manage specific users by name or other criteria without manually browsing through the entire list.

Acceptance Criteria:

1. A search input field should be available above the users table on the access management and project access management pages.
2. The search functionality should filter users in real-time as the user types.
3. The filtered results should display matching users based on the search term (e.g., name).
4. The search should be case-insensitive and allow partial matches (e.g., typing "Ann" should return both "Ann Smith" and "Anna Johnson").
5. If no users match the search term, a "No users matching your search criteria."
