refactor: 优化优先级管理和路由展示功能

- 支持按 API 格式设置不同的全局优先级，替换单一 global_priority 字段为 global_priority_by_format
- 路由标签根据调度模式动态显示（缓存亲和/负载均衡/固定顺序）
- 优先级管理对话框 UI 优化：紧凑布局、活跃/停用状态分组排序、快捷启用/禁用开关
- 优先级管理对话框包含所有 Key（含停用的），支持快速切换状态
- 优化配置更新流程：先保存优先级数据，再切换调度模式，避免瞬态不一致
- 调度相关配置缓存 TTL 从 60 秒降至 5 秒，确保多 Worker 快速收敛
- 配置更新时立即同步当前 Worker 的 Scheduler 状态
