Board: all people visible in the name picker, PIN enters itself, no number before shopping items

- Name picker wraps in a wider box so five or more people fit
- The board knows each PIN's length and submits when the last digit is typed
- Shopping items typed in are added with no quantity and shown without Mealie's leading 1
- Test updated
