Let the chart window be picked: 7, 14 or 30 days (default 7)

A 7d/14d/30d picker in the charts card sets how many days every
rolling chart covers — daily bars, sleep timeline, hour heatmap and
training consistency grid. The choice is stored per device like the
theme; headers show the current window, day labels thin out and bar
gaps tighten as the window widens, and the sleep timeline grows rows
to fit.
