 * `/trips/new` is no longer a page for brokers, carriers or pilot dispatch —

 * dashboard you click on the button, the right link should open"):
 *   freight broker  → /fb-new-trip  (or /fb-new-trip-request without ?mode=trip)
 *   carrier dispatch → /cd-new-trip
 *   pilot dispatch  → /pd-new-trip
 * Old links keep working through this redirect.
