trucking: pass-through fee disclosure + state fulfillment status machine

Item 2 of the trucking state-authorization plan.

- compliance-orders.ts: populate gov_fee_label for every state-trucking
  service so the variable, billed-at-cost government charges (apportioned
  IRP, IFTA decals, NY HUT, CT HUF, weight-distance, CA MCP+CARB, OS/OW
  permits, bundle) are disclosed at checkout. price_cents stays the flat
  service fee; gov fees pass through at cost.
- migration 086: compliance_orders.fulfillment_status state machine
  (authorization_required -> authorization_signed -> awaiting_customer_
  delegation -> awaiting_secure_credentials -> awaiting_government_fee_
  approval -> awaiting_insurance_filing -> ready_to_file ->
  filed_waiting_state -> completed) + fulfillment_status_at
- state_trucking.py: FULFILLMENT_* constants + _set_fulfillment_status();
  gate sets authorization_required on pause, authorization_signed on
  resume, ready_to_file once the filing todo is queued
- TruckingValueNotice.astro: 'What's included & what's billed at cost'
  disclosure with the authorization/delegation explanation

+          The price shown is <strong>our flat service fee</strong> to prepare and
+          submit this filing for you. Government charges are passed through
+          <strong>at cost</strong> &mdash; we never mark them up. Depending on your
+          fleet weight, mileage, and base state, the state may charge:
+        </p>
+        <ul>
+          <li>government registration, account, decal, and permit fees;</li>
+          <li>weight-distance / highway-use taxes you owe to the state;</li>
+          <li>card processing fees, and any bond, deposit, or insurance filing cost.</li>
+        </ul>
+        <p>
+          Where these amounts are not known at checkout, we bill them separately at
+          cost once the state issues its invoice &mdash; with your approval before
+          we remit anything.
+        </p>
+        <p class="pw-tvalue-note">
+          To file on your behalf we will email you a short <strong>authorization to
+          sign</strong>. It lets Performance West prepare and submit your filing,
+          communicate with the agency, and remit the government fees you provide. If
+          the state requires it, we may ask you to add us as a portal user/delegate
+          or securely share account access.
