Add end-to-end integration tests for Vaultik
- Create comprehensive integration tests with mock S3 client - Add in-memory filesystem and SQLite database support for testing - Test full backup workflow including chunking, packing, and uploading - Add test to verify encrypted blob content - Fix scanner to use afero filesystem for temp file cleanup - Demonstrate successful backup and verification with mock dependencies
