Animate the ETA, hide delays, and tidy the order card actions

- Slide the "Ready in about" value when it changes (new EtaMessage)
- Drop the "Running late" banner; delays only move the ETA now
- Remove the cancel-info tooltip and its icon button
- Shorten the steps toggle to "Steps" / "Hide"
- Add icons and more padding to the order card action buttons
