Polish the New Workout form: segmented When on top, pushed routine list

- When section moves to the top as a segmented control (3 or 4 segments
  depending on whether Now is offered)
- Routine selection is a pushed list with each routine's symbol and color,
  checkmark on the current pick, select-and-pop
- Goal "None" reserves the symbol slot so all goal labels align
