Did you read the Contributor Guide?

• Yes, I have read the Contributor Rules and Contributor Development Guide

Is this PR related to a ticket?

• Yes, and the PR name follows the format [GH-XXX] my subject. Closes bug: ST_AreaSpheroid returns wrong result sometimes #2603

What changes were proposed in this PR?

ST_AreaSpheroid/Spheroid.area previously computed spheroidal area for a Polygon by feeding geom.getCoordinates() into GeographicLib PolygonArea, which flattens exterior + interior rings and can yield incorrect results for polygons with holes / complex geometries.

This PR computes area as exterior ring area minus the sum of interior ring areas (holes), by computing each ring independently.

How was this patch tested?

• mvn -pl common test
• Added a (temporary) regression test using one of the example geometries from the CSV attached to bug: ST_AreaSpheroid returns wrong result sometimes #2603, comparing Sedona's spheroidal area to the PostGIS result.

Did this PR include necessary documentation updates?

• No, this PR does not affect any public API so no need to change the documentation.
