Records: exclude Zwift activities by title; show Saved confirmation before closing drawer

- _is_outdoor now also excludes activities whose title matches /\bzwift\b/i,
  covering the ~50 Strava-imported Zwift rides that lack sub_sport metadata.

- EditDrawer waits 900ms after a successful save before dispatching 'saved'
  (which closes the drawer), so the green "Saved" confirmation is visible.
