V3-05: mounted (handlebar) mode

Wake lock via a WakelockController seam (mirrors LocationSource), gated strictly to actual recording and released on stop/discard/navigate-away/dispose. High-contrast ripprMountedTheme() applied only to the record screen. BigStat gained a scale param for the headline figure rather than a blanket TextTheme.apply, which crashes on Material 3's default theme.
