feat: add admin leads endpoint and fix routing

- Customers service: add admin.rs with GET /api/admin/leads returning requirements with customer info
- Update customers main.rs to mount admin router at /api/admin/leads (instead of /api/admin/requirements)
- Gateway: route /api/admin/leads to customers service; remove /api/admin/requirements routing
- This enables Leads Management page to fetch all platform requirements
- Removed redundant /admin/requirements list page from frontend (kept detail page)
