fix(weather cards): arrowhead needle, matched type sizes, visible rain bars

- details: the wind needle ends in a filled arrowhead instead of a dot,
  so the direction it points (where the wind goes) reads one way only.
- hourly, details, sky: raise each card's share so card.standard reaches
  the same S (72) as now and week. Title and row text now match across
  the five cards (21.6px / 23px), in line with breaktimer and calendar.
  The bands (curve, compass, arc) absorb what is left.
- hourly: band labels follow the band height a little more (capped at the
  row size), so they do not shrink with the taller header.
- hourly: rain-chance bars at half alpha with a minimum height for any
  nonzero chance. Typical chances are a few percent, which scaled honestly
  is a 1px bar that no alpha can rescue.
- now: the condition line sits on the card's foot, so the height the
  capped type leaves over is not an empty strip at the bottom.
