add CreditCard faker with comprehensive card data generation

Introduces a new CreditCard faker that generates realistic credit card test data including:
- Card numbers with valid Luhn checksums for all major card types
- CVV codes (3 digits standard, 4 for Amex)
- Expiration dates (future and expired)
- Cardholder names in uppercase format
- Issuing bank names
- Masked card numbers for display
- Network name lookup

The implementation delegates to Finance.creditCard() for Luhn validation while
providing a dedicated API with expanded functionality beyond the existing
Finance methods.

All 18 tests pass. Includes specification documentation and learnings from
implementation mistakes to help future contributors.
