fix: CI failures — QR test timeout and Python dependency CVEs

- Increase QR generate max-size test timeout to 120s (10000x10000
  PNG generation exceeds 30s default on CI runners)
- Update Pillow 11.1.0 → >=12.2.0 (CVE-2026-25990, CVE-2026-40192)
- Update rembg 2.0.62 → >=2.0.75 (CVE-2026-40086)
- Update opencv-python-headless to flexible range >=4.10,<4.12
- Ignore CVE-2024-27763 in pip-audit (basicsr transitive dep from
  realesrgan, no fix available upstream)
- Align requirements-gpu.txt and Dockerfile with same versions
