fix: SaaS Admin + Tauri 一致性审查修复

- 删除 webhook 死代码模块 (4 文件 + worker，未注册未挂载)
- 删除孤立组件 StatusTag.tsx (从未被导入)
- authStore 权限模型补全 (scheduler/knowledge/billing 6+ permission key)
- authStore 硬编码 logout URL 改为 env 变量
- 清理未使用 service 方法 (agent-templates/billing/roles)
- Logs.tsx 代码重复消除 (本地常量 → @/constants/status)
- TRUTH.md 数字校准 (Tauri 177→183, SaaS API 131→130)
