feat(media): 重构媒体下载，支持 xhs/dy/ks/bili/wb 五平台

旧实现只覆盖 4 个平台，且把整个文件读进内存、无重试与完整性校验，
代码按平台复制粘贴了 4 份。本次用统一下载器替换：

- 新增 media_downloader/：流式写入、Range 续传、指数退避重试、大小校验、
  路径穿越防护；B 站 DASH 音视频分轨下载后交由 ffmpeg 无损合流
- 新增 media_platform/<平台>/media.py：从平台原始响应提取媒体地址，
  与下载器解耦；快手首次接入下载能力
- 开关：config.ENABLE_GET_MEDIA 与 --get_media，并打通 API/WebUI；
  同时修正旧配置项 ENABLE_GET_MEIDAS 的拼写
- 落盘按帖子聚合：{SAVE_DATA_PATH 或 data}/{platform}/media/{内容ID}/
- B 站装好 ffmpeg 时走 DASH 最高画质，否则降级 mp4 直链（产物 video-durl.mp4，
  避免低清文件阻塞后续的高清路径）
- 删除 4 个 *_store_media.py、AbstractStoreImage/Video 及各 client 的媒体 GET 方法

媒体下载失败只记录日志，不中断爬取主流程。

Keep PR 900 overrides bounded and opt-in

The PR adds API limit overrides and static proxy support, but the review found that the default proxy provider changed to an invalid static placeholder and the new API fields accepted unbounded values. This keeps the existing proxy default intact, makes static proxy explicit via config or CLI, validates API limit ranges, and adds focused regression coverage for both paths.

Constraint: PR branch must remain contributor-branch compatible and avoid adding dependencies

Rejected: Keep static as the default provider | breaks existing --enable_ip_proxy defaults with an invalid placeholder URL

Rejected: Accept arbitrary integer limits | lets API callers request negative or excessive crawl sizes

Confidence: high

Scope-risk: narrow

Directive: Do not change proxy provider defaults when adding new providers; new providers should be opt-in and covered by provider-specific tests

Tested: uv run pytest tests/test_api_limits.py tests/test_static_proxy_provider.py

Tested: uv run pytest tests

Tested: uv run pytest test/test_utils.py

Tested: uv run python -m compileall api cmd_arg config proxy tests

Tested: git diff --cached --check

Not-tested: Live crawler run against external platforms or real proxy vendor endpoints
