fix: auto-override hostname to 'integrationtest' in integration test mode

- When DTAIL_INTEGRATION_TEST_RUN_MODE is set, hostname is automatically
  set to 'integrationtest' for consistent test behavior
- Updated dcatcolors.expected to include trailing newline
- All integration tests now pass without turbo mode enabled
