Recharts ignores the `interval` prop on `<XAxis type="number" />`.
The pulse + mood charts switched to numeric axes in v1.4.25 to
support multi-band rendering, which silently degraded the
day-aware density policy to "every tick" on those charts. On a
365-row pulse view that meant ~365 overlapping labels.
Add `computeTickPositions(chartData, viewportWidth)` — translates
the existing `chooseTickInterval` skip count into explicit indices
the numeric axis consumes via the `ticks` prop. Tick count clamps
to a 3-12 visible-label range so dense series don't overcrowd and
sparse series don't collapse to a single label.
The category-axis charts (`compliance-line-chart`,
`medication-compliance-chart`) stay on `interval` — Recharts
honours it there.
