Fix DNS PSF: use @SEGMENT.SEQUENCE instead of @SEGMENT.ROLES for frame creation

- Changed from ROLES format to SEQUENCE format matching dns_google_com.psf
- PSF parser expects SEQUENCE with ROLE/PHASE/FORMAT structure
- This fixes 'Failed to create frames for protocol: dns' error on server
- DNS queries fake google.com lookups for Iran DPI evasion
