feat: add Compose setting to disable Health Connect workout suggestions

Adds a "Suggest workouts to share" toggle under Compose Settings (defaults on,
preserving current behavior) wired through UiSettings / UiSettingsFlow /
UiSharedPreferences. When set to NEVER, the Workouts screen no longer scans
Health Connect or shows the connect/suggestion banner.
