nickviljoen f83b4fae3e PPR Environment: Use SIMPLE metadata structure for tabular fields 
Key Changes:
- Updated metadata_extractor_mvp.py to use SIMPLE structure for all tabular fields
- All tabular fields now use direct value objects (no MetadataTableFieldRow wrapper)
- MAIN_LANGUAGES, ASSETCOMPLIANCE, MARKETING_TAG, CREATIVEX all use SIMPLE structure
- Master Asset ID field updated to SIMPLE structure
- Date fields now use type 'string' instead of 'long'
- Matches DAM reference structure from asset_representation.json

Added Files:
- metadata_extractor_mvp_PROD.py: PROD-specific version with same SIMPLE structure
- Backup files for safety
- Analysis and comparison documentation

Environment:
- Tested and working in PPR environment (ppr.dam.ferrero.com)
- All tabular fields match DAM-supplied reference structure
- Successful uploads confirmed

## Analysis Methodology
### Reference File
**Path:** `/Users/nickviljoen/Downloads/asset_representation.json`
**Source:** Client-provided reference payload
**Fields:** 31 total fields
### Code Base
**Path:** `/Users/nickviljoen/Desktop/Ferrero/ferrero-opentext/Python-Version/scripts/shared/metadata_extractor_mvp.py`
**Primary Function:** `build_mvp_asset_representation()`
**Lines:** 86-148 (main), supporting functions through line 818
### Fields Analyzed
**Total:** 14 fields (45% coverage)
**Breakdown:**
- 5 Tabular fields (100% of type)
- 3 Domain fields (representative sample)
- 2 Date fields (100% of type)
- 2 Text fields (representative sample)
- 2 System fields (representative sample)
**Coverage:** All field types represented
---
## Key Findings
### Perfect Matches ✅
1. **All Tabular Fields** (5/5)
- Correct MetadataTableField type
- Correct parent_table_id references
- Correct DomainValue/CascadingDomainValue types
- All properties present
2. **All Domain Fields** (3/3)
- Full DomainValue wrapper
- All 10 properties present
- Correct active_from/active_to values
- Correct display_value logic
3. **All Date Fields** (2/2)
- Correct string type (not date object)
- Correct MM/DD/YYYY format
- Proper value nesting
4. **All Text Fields** (2/2)
- Simple value.value structure
- String type
- No extra wrappers
### Minor Differences ⚠️
1. **System Fields** (2/2)
- Missing: cascading_domain_value, domain_value, is_locked at top level
- Impact: Minimal (system fields, likely added by DAM)
- Recommendation: Optional enhancement
2. **Property Order**
- Different order in nested objects
- Impact: None (JSON objects are unordered)
- Recommendation: No action required
