feat: add vision support validation for image processing

- Introduced a new method in ProviderFactory to check if a model supports vision/image input.
- Updated AgentService and AutoModeService to validate vision support before processing images, throwing an error if the model does not support it.
- Enhanced error messages to guide users on switching models or removing images if necessary.

These changes improve the robustness of image processing by ensuring compatibility with the selected models.
