fix(gotjunk): Add safety verification for classification modal

[Foundup]

Summary

Adds automatic safety verification to ensure the classification modal (Free/Discount/Bid) always appears and waits for user selection before posting images.

Problem

User reported: "when I take a pic sometimes the selection option doesn't happen"

The classification modal would sometimes:

• Not appear after photo capture
• Get accidentally dismissed
• Close without user making a selection

Result: Photo captured but user unable to classify and post it.

Solution

Implemented 3-layer safety verification system:

1. Backup Storage

Added refs (App.tsx:103-104):

const pendingClassificationBackupRef = useRef<{...} | null>(null);
const classificationCompletedRef = useRef(false);

Stores captured photo data as backup when photo is taken.

2. Safety Monitor

useEffect watcher (App.tsx:106-122):

useEffect(() => {
  if (!pendingClassificationItem && pendingClassificationBackupRef.current && !classificationCompletedRef.current) {
    console.warn('[GotJunk] SAFETY CHECK: Classification modal closed without selection! Restoring...');
    setTimeout(() => setPendingClassificationItem(backup), 100);
  }
}, [pendingClassificationItem]);

Monitors when pendingClassificationItem changes. If it disappears without classification completing, automatically restores the modal after 100ms.

3. Completion Tracking

Mark success (App.tsx:309-310):

classificationCompletedRef.current = true;
pendingClassificationBackupRef.current = null;

When user successfully selects Free/Discount/Bid, marks classification as completed and clears backup.

Debugging

Console output added for troubleshooting:

• "[GotJunk] Photo captured - opening classification modal" - Photo captured
• "[GotJunk] SAFETY CHECK: Classification modal closed without selection! Restoring..." - Modal disappeared unexpectedly
• "[GotJunk] SAFETY RESTORE: Re-opening classification modal" - Modal restored

Testing

Before:

• Take photo → Sometimes no modal appears → User stuck
• Modal appears → Accidentally dismiss → Photo lost

After:

• Take photo → Modal ALWAYS appears ✓
• Modal disappears accidentally → Auto-restores after 100ms ✓
• User MUST classify before image is posted ✓

User Experience

This ensures users can NEVER lose a captured photo. The modal will keep re-appearing until they make a classification choice (Free/Discount/Bid).
