Magic Link Exchange
Request
This endpoint expects a multipart form.
lt
Required: The single-use signed magic-link token extracted from the `lt` query param on a CTA URL (e.g. https://app.itspropel.com/cta?...<=eyJ...). Single-use, 15-min TTL from email send. Any failure mode (expired, tampered, replayed, user-gone) returns the same generic 422 — do not try to distinguish.
device_name
Optional: Label for the issued Sanctum token (shows in /auth/session device list). Defaults to “magic-link” if omitted.
