Refactor controllers to use httpx for JSON responses and eliminate context dependency

- Updated TagController methods to use httpx.WriteJSON for consistent JSON response handling.
- Refactored TicketController to replace context-dependent methods with standalone functions using httpx.
- Modified UserController to utilize httpx for error handling and response formatting.
- Adjusted WechatController to remove context dependency and standardize response handling.
