Fix getFunctionLogs orderBy parameter with proper enum validation

- Update TypeScript implementation to use enum validation for order and orderBy fields
- Add enum constraints to JSON schema for type safety
- orderBy now only accepts: function_name, duration, mem_usage, start_time
- order now only accepts: desc, asc
- Enhanced field descriptions with explanations
- Prevents API errors like "OrderBy取值与规范不符" when using invalid values like "RequestTime"

Fixes #64
