Trial extension — before / after dates

/**
 * Trial-extension offer that shows the *transition* — the current end date,
 * an arrow, and the new end date — instead of just the days gained. Reads
 * more "before / after" than "+N days." Use it when the actual dates
 * matter to your customer (billing pipelines, planned launches, deliverable
 * deadlines).
 *
 *   <CancelFlow
 *     ...
 *     components={{ TrialExtensionOffer: TrialExtensionDateArrow }}
 *   />
 *
 * Pass `currentEndsAt` as a `Date` via `step.data` or close over your own
 * billing data when you instantiate the override — the demo below assumes
 * the trial ends today.
