perf(insights): bound the medication-intake reads to the rendered window

general-status and blood-pressure-status read the full medication-intake
history with no time floor, scanning every row for accounts with years of
data. Both only consume the trailing ~365 days (the adherence fold and the
continuity series / 7-30 day compliance gate), so add a scheduledFor floor at
now - 365d.
