Release 4.233.0

ov-metrics.js on a phone, and prices under a dollar.

• A narrow table is cards (OVMetrics.table):
  • in a box under 520 px wide (a container query, so a side column counts too), each row is a card: its name on top and each value under its label;
  • the column heads become a row of sort buttons, and the one in use is outlined;
  • nothing scrolls sideways;
  • the table, its rows, cells and heads carry their roles, so a screen reader still reads a table whatever the display.
• format.usd keeps two significant digits under a dollar: $0.0118 is $0.012, not $0.01; $0.25 stays $0.25. A per-call price no longer rounds away.
• Test ov-metrics-chrome: the card form at 390 px, the labels, the roles, no sideways scroll, and the new prices.
