[walmat]

What changed (plus any additional context for devs)

1. Date Formatting Refactor

New Utility Function

• Added dateFormatter utility function in SettingsSheet/utils.ts
• Provides centralized date formatting with error handling
• Uses date-fns format function with fallback to 'Unknown Date'

Implementation Changes

• Removed direct date-fns imports from component files
• Consolidated date formatting logic into a single utility function
• Default format string set to "M/d/yy 'at' h:mm a"

2. Backup File Sorting Enhancement

Error Handling

• Added try-catch blocks around timestamp parsing logic
• Returns 0 as fallback when timestamp parsing fails
• Implemented in both ChooseBackupStep and ViewCloudBackups components

Code Organization

• Improved type safety with explicit LoadingTextProps interface
• Better error handling for backup file timestamp parsing
• Consistent sorting behavior across backup-related components

3. Component Improvements

Type Safety Enhancements

• Added proper typing for theme props
• Introduced LoadingTextProps interface for better type checking
• Improved component prop definitions

This PR focuses on improving the robustness of the cloud backup system by adding proper error handling and centralizing date formatting logic. The changes make the backup system more resilient to invalid dates while maintaining consistent date formatting across the application.
