fix: geocoder coordinate search results not showing (#2245) (#3322)

When entering coordinates in the geocoder search box, the results
dropdown might not appear or could be overwritten by a pending
geocoder API call.

Fix by:
1. Clearing any pending geocoder debounce timeout when valid
   coordinates are detected, preventing stale API results from
   overwriting the coordinate result.
2. Explicitly setting showResults to true to ensure the dropdown
   is visible.
