Fix/zoom feature

[reanbrenda]

Summary

This pull request improves map interaction behavior by preventing unintended zoom-out when selecting a school point and by making school dots continue to scale at higher zoom levels for better visibility.

Related Issue

When users clicked a school point after manually zooming in, the map reset to a fixed zoom level, creating a a bad experience.
Additionally, circle markers stopped increasing in size after a certain zoom threshold, making high-zoom exploration less clear.

Proposed Changes

Proposed Changes

Fixed the zoom-out issue when clicking a school:

• If user is already zoomed in, we keep that zoom.
• We only move the map center to the school.
• Use the higher value between default school zoom and current zoom in zoomToCountryFx.

Updated map styling so circles get bigger at higher zoom levels:

• Added more zoom-size steps for circle-radius.
• Applied same update to country override settings (lk) for consistency.
