Unified DOT intake form — one form for all trucking services

Single DOTIntakeStep shows/hides sections based on services ordered:
- Company info + address + signer (always)
- Entity & operations (MCS-150, USDOT, MC Auth, bundles)
- Fleet info (MCS-150, UCR, bundles)
- UCR fleet bracket + base state (UCR)
- Cargo types (MCS-150, bundles)
- D&A program (CDL drivers, DER, consortium)
- BOC-3 docket info (BOC-3)
- Photo ID upload (MCS-150, MC Auth)
- Security/encryption notices

All DOT services now use ["dot-intake", "review"] instead of ["review"].
