feat: 实现文件类型枚举的本地化支持

新增文件类型枚举的本地化功能，包括供应商、项目、公司、合同和客户文件类型。添加了相关的SQL表结构、Repository、Service、ViewModel和StringConverter实现。同时更新了文档说明如何创建和使用枚举类型的本地化功能。

修改了客户文件类型的相关代码，统一使用CustomerFileTypeLocalVo替代原有的CompanyCustomerFileTypeLocal，优化了代码结构和一致性。添加了文件类型枚举的缓存支持，提高了性能。

更新了create_enum.md文档，详细说明了文件类型枚举本地化的实现方式和相关组件清单。
