feat(qoder): refresh model catalog, add capability mapping and image pass-through

- Registry/constants: drop qmodel_preview/gm51model, add lite,
  qmodel_38max (Qwen3.8-Max), qfmodel (Qwen3.8-Flash), gmodel (GLM-5.3),
  gfmodel (GLM-5.3-Flash)
- capabilities: add PROVIDER_CAPABILITIES['qoder'] so opaque internal
  ids resolve to their real models' context windows and limits
- executor: preserve image blocks instead of flattening away, convert
  Claude-style image blocks, and hash images into chat_record_id
- tests: cover image preservation, data-URI and Claude-block conversion
- build(docker): use CN mirrors for apk and npm
