Fix missing Presidio recognizers for URL, US_SSN, CRYPTO, etc. (#69)

Fix missing Presidio recognizers for URL, US_SSN, CRYPTO, etc. (#69)

The config generator only included 6 recognizers, missing standard ones
like UrlRecognizer, UsSsnRecognizer, CryptoRecognizer. This caused
detection failures when users enabled these entity types.

Changes:
- Add GLOBAL_RECOGNIZERS for pattern-based detection (7 recognizers)
- Add LANGUAGE_RECOGNIZERS for language-specific detection
- Only load language-specific recognizers when that language is configured
- EN: US + UK recognizers (8)
- ES: Spanish NIF/NIE (2)
- IT: Italian documents (5)
- PL: Polish PESEL (1)
- KO: Korean RRN (1)
