chore(release): v1.28.11 — Strava workouts + Garmin guidance

Adds a Strava connection (BYO app keys, per-user, mirroring the other
wearables): activities arrive as workouts, de-duplicated against other sources
by the existing source-priority picker, workouts-only. Documents that Garmin has
no direct connector and flows in via Apple Health / Google Health Connect.
