fix(know-your-world): reduce magnifier size to 1/3 of pane dimensions 

Change magnifier from 1/2 width (and 1/4 height) to 1/3 of both
container dimensions. This makes the magnifier less obtrusive since
the map is centered in the pane.

- Add MAGNIFIER_SIZE_RATIO constant (1/3)
- Update magnifierWidth to use containerRect.width * MAGNIFIER_SIZE_RATIO
- Update magnifierHeight to use containerRect.height * MAGNIFIER_SIZE_RATIO
