refactor(ui): remove unused image cache system and fix TypeScript compilation

- Remove imageCache Map that only stored null values
- Remove selectedImageData Blob property (never used)
- Remove cacheImageData method and related function props
- Remove handleImageLoad method from ActivityListItem
- Clean up ImageViewer component props
- Fix TypeScript compilation by replacing legacy logConsoleAndDb calls
- Replace logConsoleAndDb with logger.error in deepLinks service
- Images continue to work via direct URL references

The image cache system was non-functional and only stored null values.
ImageViewer component ignored blob data and only used URLs.
Fixed production build failure caused by undefined logConsoleAndDb function.
Removing dead code improves maintainability without affecting functionality.
