refactor: organize admin menu into categories

Before: 17 flat first-level items, 14 under single "系统运维"
After:  5 groups — 总览/用户管理/知识库/学习数据/系统

- AdminMenuItem.path → optional for group headers
- Breadcrumb map updated to match new structure
- Removed unused entries (hermes/servers/billing/git/etc.)
