refactor: 重构错误处理并优化路由与服务结构

主要变更：
- 新增 `app/handler/error_handler.py`，引入 `handle_route_errors` 异步上下文管理器，用于统一处理路由中的错误和日志记录。
- 在 `openai_routes` 和 `openai_compatiable_routes` 中应用 `handle_route_errors`，移除冗余的 try-except 块，简化路由逻辑。
- 将 `OpenAICompatiableService` 移动到 `app/service/openai_compatiable/` 目录下。
- 将 `StatsService` 移动到 `app/service/stats/` 目录下，并更新相关导入路径。
- 修复 `response_handler` 中处理 Gemini API 响应时 `inlineData` 字段的错误（原为 `inline_data`）。
- 修复 `openai_routes` 和 `openai_compatiable_routes` 中处理图像生成聊天（如 imagen3-chat）时未正确使用付费 API key 的问题。
- 在 `requirements.txt` 中将 `httpx` 更改为 `httpx[socks]`，以增加 SOCKS 代理支持。
