HEL-543 返工: 补充 observability 运行时可关闭开关 (DATAHUB_OBSERVABILITY)

总工复核 🔴：安全边界要求新增观测功能必须可关闭、关闭后现有功能完全照旧，但此前实现没有任何运行时开关。修复： - settings.py: 新增 Settings.observability_enabled 字段，沿用既有 DATAHUB_SCHEDULER 的环境变量模式，读取 DATAHUB_OBSERVABILITY (0/false/off 关闭，默认开启)。 - hub.py: Hub.__init__ 把 settings.observability_enabled 挂到 self.db 上，让 pipeline/realtime_serve/steward/admin_api 已经在传的 db 参数直接带上开关，零额外改造。 - observability.py: 新增 is_enabled(db)，缺失该属性时默认按启用处理 (向后兼容裸 HubDB 用例/测试)。关闭时 observe() 变成纯透传（不计时、不分类、不碰数据库)，record_call() 直接 no-op。 - admin_api.py: 4 个新只读端点关闭时返回明确的 {"enabled": false, ...空结构} 而不是静默返回旧数据。 - 新增 10 个测试：开关默认值/环境变量解析、关闭后 observe() 的透传语义 (含异常原样重新抛出)、关闭后 record_call() 零写入、关闭后重新开启恢复记录、4 个 admin 端点在关闭态的响应结构。全量测试 183/183 通过（新增 10 个，含此前 173 个零回归）。 Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: multica-agent <github@multica.ai>
