fix: rename zhipu bot_type, persist bot_type in web config, fix re.sub escape error

- Rename ZHIPU_AI bot type from glm-4 to zhipu to avoid confusion with model names

- Add bot_type persistence in web config to fix provider dropdown resetting on refresh

- Change OpenAI provider key to chatGPT to match bot_factory routing

- Add DEEPSEEK constant and route it to ChatGPTBot (OpenAI-compatible API)

- Keep backward compatibility for legacy bot_type glm-4 in bot_factory

- Fix re.sub bad escape error on Windows paths by using lambda replacement

- Remove unused pydantic import in minimax_bot.py
