Fix Sync Screen Version Display and Status Contradictions

[najuna-brian]

Summary

Fixes confusing UX issues on the Sync screen where version information and status messages were contradictory or unclear.
Closes #146

Issues Fixed

Version Display Confusion

• Problem: App bundle versions showed "current" or "Unknown" instead of actual version numbers
• Solution: Display actual version numbers for both local and server versions
• Before: Local: current, Server: Unknown with "Update available"
• After: Local: 003, Server: 004 with logical update status

Status Message Contradictions

• Problem: Status card showed "Error" with subtext "All synced" simultaneously
• Solution: Remove contradictory subtext when error state is active
• Result: Clear, non-conflicting status messages

Authentication Error Handling

• Problem: 401 errors during app bundle updates showed generic error messages
• Solution: Add specific authentication checks and targeted error messages
• Result: Users get clear guidance when authentication issues occur

Changes Made

SyncScreen.tsx

• Modified checkForUpdates() to set server version to local version on manifest fetch failure
• Updated getDataSyncStatus() to return "All synced" instead of "Ready" for consistency
• Removed contradictory "All synced" subtext when error state is active
• Added authentication and permission checks in handleCustomAppUpdate()
• Enhanced error handling with specific 401 authentication error messages
• Maintained display of actual version numbers for better user clarity

Testing

Test with normal sync operations, app bundle updates, network failures, authentication errors, and version display scenarios.

Impact

• Improved UX: Users now see clear, consistent version and status information
• Better error handling: More informative error messages guide users to resolution
• Reduced confusion: Eliminates contradictory status displays

I think the new check for errorMessage.includes('401') with the “Your session has expired…” alert is awesome, that'll greatly improve handling of authentication expiration/Unauthorized errors.
