Support Basic No-Field Guild Ambassador shipments

Connect native concealment and allied supplier/recipient consent to the independent grant, with explicit provisional cap and transport-fee policy. Preserve actual tokens, ordinary allowances, source-scoped Karama prevention and original income/arrival continuation.

Add genuine three/four-seat sources, focused quote/control/engine cases and bounded runtime/minimal-bot proof. Advanced and optional profiles retain their existing guards.
