Polish DottedMap: glow effect, tooltips, better fill

- SVG filter for orange glow behind markers
- Hover tooltips showing country name + pageview count
- Reduced viewBox height (75→68) to fill card better
- Bumped mapSamples to 8000 for crisper landmass
- Centered map vertically with flexbox wrapper
