One Ship button on every order

An order now shows one button for what comes next, and the rest sits under More.

• Ship asks how the parcel goes: Create label at your carrier (MyParcel or Sendcloud), or Tracking number for a parcel you send another way.
• A TikTok order of several items? Ship asks which items go in this parcel. Leave some out and that parcel goes on its own label, numbered after the order ("1029-1", "1029-2"), with its own tracking number to TikTok. Ship the rest the same way.
• Under More: a payment link, Ship sealed, cancelling, a new label, a refund.
• Label prints a parcel's label again whenever you need it.
