c67378ff25 Implement encrypted transaction caching for GoCardless adapter 
- Reduces GoCardless API calls by up to 99% through intelligent caching of transaction data
- Secure AES-GCM encryption with PBKDF2 key derivation (200k iterations) for at-rest storage
- Automatic range merging and transaction deduplication to minimize storage and API usage
- Cache-first approach with automatic fetching of uncovered date ranges
- Comprehensive test suite with 30 unit tests covering all cache operations and edge cases
- Thread-safe implementation with in-memory caching and encrypted disk persistence
