feat: detect K-snake X11 in Mouse Check (VID 0xA8A4/0xA8A5)

[yanhenrique-dev]

Detect K-snake X11 (VID 0xA8A4 USB / 0xA8A5 2.4G, PID 0x2255) in Mouse Check.

• Add 0xA8A4/0xA8A5 to BRANDS so check.html labels the dongle instead of Unknown and SCAN_FILTERS offers the vendor 0xFF01 interface.
• List X11 as driver-needed in supported-mice (no protocol driver yet).

Evidence:

• Vendor WebHID panel https://x1a11.yjx2012.com/ requests [{vendorId:43172,productId:8789,usagePage:65281,usage:16},{vendorId:43173,...}] (0xA8A4/0xA8A5:0x2255, 0xFF01:0x10).
• HID Diagnostic Report from hardware (2.4G dongle): 3x USB Receiver VID_A8A5 PARTIAL, first with Vendor (0xFF01), others FFA5 / FF05+FF06. Output-report protocol (sendReport 0 + 0x55 framing), so PARTIAL is expected.

Full 0x55 codec + WebHID client draft lives locally (readStatus/setDpi/setPollingRate) and will come as a mouse-protocol PR; this PR only unblocks detection/listing.

Checks: npm run check passes (113 tests).
