Refactor image handling and decoding logic

- Introduced a maximum bitmap decode dimension to prevent excessive memory usage.
- Enhanced base64 to bitmap conversion by extracting payload and applying EXIF orientation.
- Improved error handling for image downloads and decoding processes.
- Simplified media picker and chat input components to manage keyboard visibility more effectively.
- Updated color selection grid to adaptively adjust based on available width.
- Added safety checks for notifications and call actions in profile screens.
- Optimized bitmap decoding in uriToBase64Image to handle large images more efficiently.
