fix(tests): Fix Behat integration tests - correct duplicate step definition

Fixes duplicate step definition error in Behat integration tests.

Root Cause:
EncryptionSetup trait was added to BOTH FeatureContext and CommandLineContext,
causing Behat to complain about duplicate step definitions:
'user :user has encryption keys initialized' defined in both contexts

Fix:
- Keep EncryptionSetup trait ONLY in FeatureContext
- Remove from CommandLineContext
- encryption.feature can use the step from FeatureContext

Files Modified:
- build/integration/features/bootstrap/EncryptionSetup.php (new, simplified)
- build/integration/features/bootstrap/FeatureContext.php (added trait)
- build/integration/features/bootstrap/CommandLineContext.php (removed duplicate trait)
- build/integration/files_features/encryption.feature (added init step)
