This commit completes the DRY refactoring by implementing the missing document form functionality and enhancing user experience with better error messages.
## iOS Document Forms

- Support for all warranty-specific fields (itemName, modelNumber, serialNumber, provider, etc.)
- Multiple image uploads with JPEG compression
- Proper UIImage to KotlinByteArray conversion
- Async completion handlers
- Implemented updateDocument() method with full field support
- Completed DocumentFormView submitForm() implementation with proper API calls
- Fixed type conversion issues (Bool/KotlinBoolean, Int32/KotlinInt)
- Added proper error handling and user feedback
## iOS Login Error Handling
- Enhanced error messages to be user-friendly and concise
- Added specific messages for common HTTP error codes (400, 401, 403, 404, 500+)
- Implemented cleanErrorMessage() helper to remove technical jargon
- Added network-specific error handling (connection, timeout)
- Fixed MainActor isolation warnings with proper Task wrapping
## Code Quality
- Removed ~4,086 lines of duplicate code through form consolidation
- Added 429 lines of new shared form components
- Fixed Swift compiler performance issues
- Ensured both iOS and Android builds succeed
