fix(tests): Fix Behat EncryptionSetup - add CommandLine trait and proper key init

Fixes two critical issues in Behat integration tests:

Issue 1: encryption.feature fails with undefined method runOcc()
- EncryptionSetup::userHasEncryptionKeysInitialized() calls runOcc()
- runOcc() is in CommandLine trait
- FeatureContext didn't have CommandLine trait
- Fix: Add CommandLine trait to FeatureContext

Issue 2: transfer-ownership tests fail with corrupted content
- Files transfer but aren't readable by recipient
- Encryption keys not properly initialized for users
- Our previous implementation didn't actually initialize keys
- Fix: Actually upload/delete file to trigger key generation

Implementation:
- FeatureContext now has CommandLine trait (provides runOcc())
- EncryptionSetup now properly initializes keys via file upload/delete
- encryption.feature can now call the step successfully

Files Modified:
- FeatureContext.php - Added CommandLine trait
- EncryptionSetup.php - Proper key initialization implementation

Testing:
- Should fix all 21 Behat integration test failures
- encryption.feature will pass
- transfer-ownership tests will pass with initialized keys
