Region map visualizations fail because they query the legacy `utm-geoip` index

• I have searched (https://github.com/utmstack/UTMStack/issues) for past instances of this issue
• I have verified that my UTMStack version is up-to-date

Describe the bug

Coordinate / region map chart visualizations still query a legacy
utm-geoip index that is no longer populated or shipped. The lookup fails
silently or with index_not_found_exception, so any dashboard widget that
plots events on a geographic map renders empty or errors out.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

Region / coordinate map charts should derive latitude and longitude directly
from native event fields (geo_point-typed fields on the alert / event
document) and stop referencing the dead utm-geoip index entirely.

Current Behavior

Region map widgets render with no data; backend logs show repeated
index_not_found_exception or empty result sets for the utm-geoip
lookup.

Reproduction Steps

1. Open a dashboard that contains a region map / coordinate map
   visualization (or create one).
2. Configure it to plot events by geographic location.
3. Observe an empty map and / or OpenSearch index-not-found errors in the
   backend logs.
