Subject: [PATCH] feat: add Prev/Next navigation buttons to /refractor status
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- RefractorPaginationView with ◀ Prev / Next ▶ buttons
- Buttons re-fetch from API on each page change
- Prev disabled on page 1, Next disabled on last page
- Only the command invoker can use the buttons
- Buttons auto-disable after 2 min timeout
- Single-page results show no buttons
