feat: record the source app/device name from Health Connect

Instead of a generic "health_connect" source, capture the app/device that wrote
the record (the Health Connect data origin) and use it as the workout source —
so the card shows e.g. "SAMSUNG HEALTH" / "GOOGLE FIT" instead of "HEALTH
CONNECT".

resolveSourceName resolves the data-origin package to the installed app's
label, falling back to a known-package map (Samsung Health, Google Fit, Fitbit,
Garmin, Strava, Nike Run Club), then the raw package, then "Health Connect".
DetectedWorkout carries this as `source` and it flows into the published kind
1301 source tag.
