♻️ refactor(setting): move API info functions to dedicated module

Move validateApiInfo and getApiInfo functions from controller layer to
setting/api_info.go to improve code organization and separation of concerns.

Changes:
- Create setting/api_info.go with ValidateApiInfo() and GetApiInfo() functions
- Remove validateApiInfo function from controller/option.go
- Remove getApiInfo function from controller/misc.go
- Update function calls to use setting package
- Clean up unused imports (net/url, regexp, fmt) in controller/option.go

This refactoring aligns the API info configuration management with the
existing pattern used by other setting modules (chat.go, group_ratio.go,
rate_limit.go, etc.) and improves code reusability and maintainability.
