[Maintenance] - No Car filter on Reimbursement Requests Page

Description

We want to remove the car filtering from the reimbursement requests page, so that users can view all requests at once, regardless of which car they have selected.

Acceptance Criteria

• reimbursement requests page does not filter by car, and shows all reimbursement requests

Proposed Solution

• update backend endpoints (getCurrentUserReimbursementRequests, getCurrentUserAssignedReimbursementRequests, getCurrentUsersTeamsReimbursementRequests, getAllReimbursementRequests) to remove carNumber parameter (reimbursement-requests.service and controller)
• update corresponding hooks (finance.hooks.ts) to no longer use carNumber

Mocks

No response

Locate the reimbursement-requests.service and controller endpoints named in the issue, then inspect finance.hooks.ts to trace how carNumber is passed through. Remove the car-based filtering across these endpoints and hooks, and verify that the reimbursement requests page shows all requests regardless of the selected car.
