feat(replay): HC-mode coverage for scrub track + notches
The 1 px scrub track and 5 quarter-mark notch ticks paint their shape via BackgroundColor (not BorderColor — they're tiny full-bleed Nodes, not borders on wider containers), so the existing HighContrastBorder marker doesn't apply to them. Add a parallel primitive in ui_theme: HighContrastBackground marker carrying default_color, mirroring HighContrastBorder's shape exactly. Add update_high_contrast_backgrounds system in settings_plugin alongside update_high_contrast_borders — same on/off rule (off → marker.default_color, on → BORDER_SUBTLE_HC), same change-suppression idiom (only mutate when different so Bevy's change-detection doesn't trigger per-frame repaints). Tag the scrub track Node and all five notch Nodes with HighContrastBackground::with_default(BORDER_SUBTLE) so the existing settings repaint cycle picks them up under HC mode. The scrub fill (ACCENT_PRIMARY brick-red) and WIN MOVE marker (STATE_SUCCESS lime-green) don't get the marker — accent and state colours are already saturated and don't need an HC luminance variant. 2 new tests: spawn-time marker presence on the track and cardinality-matches-notch-count on the ticks. Tests: 1250 → 1252. Clippy clean. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
