Refactor GeoIP data handling to ensure consistent coordinate propagation

- Updated the logic in the geo enrichment process to fill in geographic coordinates even when they are 0.0, enhancing map visualization.
- Modified the GeoIP lookup function to always return latitude and longitude, improving the accuracy of location data for the UI.
- Improved comments for clarity regarding the importance of geographic data in the mapping context.
