feat: add national_dex_number OCR extraction with proper formatting

ENHANCEMENT: Complete Pokemon data extraction coverage
- Added national_dex_number OCR extraction in parallel async pipeline
- Proper validation: 1-1400+ range, positive numbers only
- Auto-formatting: 0-padded to 4 digits (e.g., "0001", "0150", "1000")
- Integrated into PokemonInfo data structure

Technical details:
- Range validation prevents negative/invalid numbers
- String.format("%04d") ensures consistent 4-digit padding
- Follows same async pattern as other OCR extractions
- Added to parallel coroutine processing for performance

Now extracts ALL Pokemon data fields:
✅ 12 OCR fields: nickname, species, level, language, nature, ability,
   moves, types, stats, trainer info, national_dex_number
✅ 32 pokeball types, 18 tera types, 12 game stamps
✅ Alpha marks, origin marks, gender, shiny detection
