Fetch and parse the latest-used Nightscout profile (basal schedule, ISF,
carb ratio, DIA, targets) and show it as a new dashboard page: a list of
basal/ISF/carb-ratio segments plus a bar chart of basal rate by hour of
day. This is the data foundation for treatment overlays on the glucose
charts and the redesigned PDF report in follow-up PRs.
