📊 Add comprehensive answer validation interface for accuracy monitoring

**Restored Missing Validation Column:**
- Added "Correct Answer" column displaying expected answers from validation data
- Added "Match" column with visual indicators:
- ✅ = Exact match (case-insensitive)
- 🟡 = Partial match (substring matching)
- ❌ = No match or error

**Enhanced Validation Features:**
- Loads validation data from gaia_validation_metadata.jsonl
- Real-time answer comparison during processing
- Detailed match logging for performance analysis
- Graceful fallback when validation data unavailable

**Interface Improvements:**
- Updated results table label to "Detailed Question Results with Validation"
- Added validation legend to user instructions
- Applied to both root and deployment app versions consistently

**Technical Details:**
- Case-insensitive string matching for robustness
- Substring matching for partial credit detection
- Supports multiple validation file locations
- JSON parsing with error handling

This restores the validation functionality from commit 7724e0ec51435b950a6ea341fee67a3fce051261
and enables real-time accuracy monitoring during evaluation runs.
