Enhance map functionality and display of IP data

- Introduced a point counter for the map to show the number of IP locations displayed, improving user feedback.
- Updated the map rendering logic to handle cases where the map or layers are not yet initialized, preventing potential errors.
- Improved coordinate handling by ensuring latitude and longitude values are properly validated and converted to numbers.
- Enhanced the map's initial view settings to provide a better user experience when displaying points.
