fix(reader): correct the QR reader's identity — Dingtian DT-008, not "GEE"

An early wrong assumption named the QR/RFID access reader "GEE" /
"GEE/Fondvision" / "GEE-QR-ER80" (and summarized a raw GEE PDF as its
datasheet). There is no GEE device — it's the Dingtian DT-008
(dingtian-tech.com/en_us/qr_code_reader.html), the same vendor as the relay
board, which is why it integrates the identical HTTP-GET-push way.

Code:
- Driver symbol geeQrReaderDriver → dingtianQrReaderDriver; label →
  "Dingtian DT-008 QR/RFID reader (HTTP push)"; comments/description rewritten
  to the real DT-008 facts (Wiegand 26/34, TCP/IP, USB, RS485 — not RS-232;
  QR/barcode + ID/IC/NFC — not DataMatrix/1D).
- Persisted driverId "gee-qr-reader" → "dingtian-qr-reader" (the registry
  lookup key + the row created on assign in qr-reader.ts).
- Migration 0015 rewrites existing devices.driver_id rows so configured readers
  keep resolving (applied to the dev DB — 2 rows; the booth applies it on boot).
  Behaviour is unchanged: naming + the persisted id only.

Wiki + memory:
- Renamed entities/gee-qr-er80.md → dingtian-dt008-reader.md and
  sources/gee-qr-er80.md → dingtian-dt008.md; rewrote both to the real DT-008
  product-page specs while KEEPING all the verified-on-hardware protocol facts
  (cjihao serial, .jsp path, Connection: close). Fixed every cross-reference +
  "GEE" mention in 6 other pages. Memory gee-reader-serial-binding →
  dingtian-reader-serial-binding. The only surviving "GEE" mentions are
  deliberate naming-correction notes, the raw PDF filename, and the
  append-only log history.

Full workspace build/lint/test green; dev DB readers verified resolving to the
registered dingtian-qr-reader driver.
