refactor(overview): Thread isPro/onUpgrade into pod cards (groundwork)

Groundwork for a future pro indicator on the overview card's ANC mode selector. Adds isPro + onUpgrade parameters to OverviewScreen, PodDeviceCard, DualPodsCard, SinglePodsCard (currently unused inside the cards, defaults keep existing previews working). Wraps AncModeSelector in a Box as a scaffold for an overlay. Bumps surfaceContainerLowDark to match surfaceContainerDark in all three theme palettes (Amber/Blue/Green) across standard/medium/high contrast. No user-facing change yet.
