Surface shipped data sources in onboarding and tell the truth

Rewrite the source step to list the live integrations (Apple Health,
WHOOP, Oura, Polar, Nightscout, Fitbit) alongside Withings and manual
entry, each linking to where it is connected; drop the stale Apple
Health coming-soon badge. Add an import affordance for existing history.

Reword the goals and source copy so it no longer promises automatic
dashboard or reminder configuration that does not happen yet. Add a
calibration line to the done screen setting the expectation that some
insights sharpen over the first weeks, and lead the success screen
forward with connect-a-device and log-first-measurement actions.

Generalize the dashboard checklist data-source item so any connected
integration satisfies it, not Withings alone.
