Add terminate-only STIR/SHAKEN option across RMD pipeline

STIRShakenStep intake:
- New "Terminate only" option for carriers that only receive pre-signed
  calls and don't originate
- Contextual hints for each option explaining requirements
- Show/hide vendor and upstream fields based on selection

RMD letter generator:
- New terminate_only section explaining verification-only posture,
  citing 47 CFR § 64.6301 (signing obligation on originating provider)
- Added to needs_exhibit_a list

RMD Exhibit A generator:
- New terminate_only STIR/SHAKEN paragraph with SBC verification language
- Fixed scope paragraph: wholesale/facilities carriers no longer get
  "small provider without Class 4 switch" boilerplate
- Fixed OCN paragraph: wholesale carriers get neutral wording instead
  of "no OCN required for small retail provider"

RMD filing handler:
- Maps stir_shaken_status to rmd_option for Exhibit A generation
- Passes entity metadata (ocn, wholesale, gateway, contact) to generator
- Maps terminate_only → partial_implementation for FCC RMD form radio
