Mobile input tweaks (#9686)

- Buttons are marked as `touch-manipulation` so double-tapping on them
doesn't initiate a zoom.
- Move scrubable inputs to usePointerSwipe
- Strangely, swipe direction was inverted on mobile. This solves the
issue and simplifies code
  - Moves event handlers into the scrubbable input component
- Make the slightly bigger buttons only apply when on mobile.
- Updates the workflows dropdown to have a check by the activeWorkflow
and truncate workflow names
- Displays dropzones (for the image preview) on mobile, but disables the
prompt to drag and drop an image if none is selected.
