Filter repairs from repairer request list

## Basic Information
- Add to `/api/event/[id]/repair-request` to filter by status
- This will take an array of `RepairStatus`es
- On the page, only show repair requests that are `PENDING` and `ACCEPTED`
- The request body might look like ```{ status: ["PENDING", "ACCEPTED"] }```

## Other Information
- Stretch goal, add the ability to filter and toggle the visibility of these on the frontend

Start at /api/event/[id]/repair-request and trace the repairer request list page, looking for the existing RepairStatus handling and request loading code. The work is done when the endpoint accepts a status array and the page shows only PENDING and ACCEPTED requests; the frontend visibility toggle is identified as a stretch goal.
