refactor!: uv 管理环境 + 彻底删除技术债(Flask 与 requests 全部移除)

## uv 环境管理
- pyproject.toml 声明 dependencies + [dependency-groups].dev,uv.lock 精确锁定
- 删除 requirements.txt / requirements-fastapi.txt / requirements-dev.txt
- .python-version = 3.12;Dockerfile 改用 uv sync --frozen(可复现构建)
- 新增 jinja2(首页渲染)

## 删除 Flask 技术债
- 从 main.py 用 ast 精确剥离 56 个 Flask 节点(路由/中间件/错误处理/启动),
  框架无关的服务层落为 services/runtime.py(MusicAPIService、下载/打包 worker、
  任务监控、缓存清扫),零 Flask 依赖
- 删除 main.py(4527 行)与 auth_routes.py(1050 行)
- auth_system.py 移除会话/请求上下文层(login_session/current_user/login_required/
  admin_required/_client_ip 等),保留数据与业务层
- 新增 core/net.py(IP 解析)、web/auth_state.py(登录锁定/2FA 票据/发码限流)
- FastAPI 侧改直接依赖 services.runtime,不再 import main
- web/app.py 去掉 Flask fallback;入口默认根路径模式(API_PREFIX 可选)

## 删除 requests 技术债
- 新增 core/sync_http.py:requests 风格的同步门面(底层 aiohttp 连接池,
  流式读取经有界队列背压),含 Session/headers/(connect,read) 元组超时兼容
- core/utils、auth_system、podcast_api、music_downloader、services 全部切换
- 实测真实下载 5.2MB 音频完整成功

## 质量门禁归零
- ruff:0 错误(B904 全部修复,不再忽略)
- pyright:0 错误(类型收窄修复)
- pytest:140/140(含 golden 契约回归、root 模式 66 项路径覆盖)
- 真实 uvicorn 启动:/health、/、/static、受保护端鉴权全部正确

新增 tests/golden/responses.json:删除 Flask 前捕获的 32 例响应快照,
FastAPI 逐字段复现——删除巨石后行为回归仍有硬证据。
