Refactor localization strings to use constant for text domain; add image context limit feature

- Updated localization strings in various classes to use the constant `GROQ_AI_PRODUCT_TEXT_DOMAIN` instead of hardcoded text domain.
- Introduced an image context limit setting in the settings manager and adjusted related methods to accommodate this new feature.
- Modified prompt builder to handle image context limit when building product context blocks and retrieving image payloads.
- Enhanced error handling and response structures to include new fields related to image context.
- Added support for title suggestions in the structured response from the AI.
