refactor: Restructure ApifoxService with dependency injection and MCP integration

- Move APIFOX_TOKEN to index.js and pass via config object to ApifoxService
- Convert ApifoxService to accept config object with projectId, token, and baseUrl parameters
- Move axios instance creation from module level into ApifoxService constructor
- Replace global http client references with instance-based this.http throughout service methods
- Initialize ApifoxService in index.js with environment variables
- Remove GitLab API client code and replace with Apifox-focused tool implementations
- Simplify MCP server tool registration to use ApifoxService methods
- Add init() call in ApifoxService constructor for future initialization logic
- Improve code organization by centralizing API client configuration within service class
- Enable better testability and configuration flexibility through dependency injection pattern
