revert: 恢复 expense API路径与 gateway 配置保持一致

架构说明:
- 前端 baseURL: /fund
- 网关路由：Path=/fund/exp/**
- StripPrefix=1: 去掉/fund 前缀
- PrefixPath=/api/v1: 自动添加/api/v1 前缀
- 后端 Controller: /api/v1/exp/expense-type

请求流程:
前端：GET /fund/exp/expense-type/page
网关：匹配 Path=/fund/exp/** → StripPrefix=1 → PrefixPath=/api/v1
后端：接收 /api/v1/exp/expense-type/page ✓

与其他模块保持一致:
- customer: GET /customer/page → /api/v1/customer/page
- project: GET /project/page → /api/v1/project/page
- expense: GET /exp/expense-type/page → /api/v1/exp/expense-type/page

设计原则:
- 前端不硬编码/api/v1，由网关统一处理
- 符合网关路由与 API路径分离的架构设计
