Subject: Add type safety to field system with FieldType alias

- Define FieldType as typed alias for [2]byte to improve type safety
- Update all 47 field constants to use FieldType instead of raw [2]byte
- Update Field struct to use FieldType for Type field
- Update function signatures: NewField, GetField, Transaction.GetField
- Fix field_test.go to use new FieldType in test cases
- Maintains backward compatibility with zero runtime overhead
- Enhances API clarity and prevents accidental field type misuse
