Fix honeycomb grid sizing, alpha, and stroke styling

- Fix hex sizing to use aspectRatio layout instead of GeometryReader
- Remove hardcoded height estimation that caused gap between header and grid
- Set fill alpha to 0.3 and add 0.7 alpha stroke on colored hexagons
- Use 12 rows consistently
- Add forceRefresh parameter to getResidence
