Pull request overview
This pull request enhances the World.GetStatisticalRegion method to support both UN M49 region codes and country codes, and adds comprehensive test coverage for all valid UN M49 codes. The change improves the method's robustness by implementing a fallback mechanism that checks the countries dictionary when a code is not found in the regions dictionary.
Changes:
- Modified
GetStatisticalRegionto first checkRegionsByCode, then fall back toCountriesByCodeif not found - Added parameterized unit test covering 249 UN M49 codes to ensure all valid codes return non-null results

137-416: Consider moving the UN M49 list out ofInlineDatainto a shared data source.This test is valid, but the very large attribute block is expensive to maintain. A
MemberDatasource keeps the same behavior with easier updates.♻️ Suggested refactor

Verify each finding against the current code and only fix it if needed. In `@test/Cuemon.Core.Tests/Globalization/WorldTest.cs` around lines 137 - 416, The test GetStatisticalRegion_ShouldReturnNonNullResult_ForAllUnM49Codes contains a huge InlineData block; extract the UN M49 codes into a shared data provider and switch the test to use MemberData (or ClassData) instead: create a static IEnumerable<object[]> property or method (e.g. UnM49Codes or UnM49Data) that yields each code string, update the Theory attribute to [MemberData(nameof(UnM49Codes), MemberType = typeof(YourTestClassOrHelper))], and remove the InlineData entries so the test behavior remains identical but the data list is maintained in one place for easier updates.

GetStatisticalRegion_ShouldReturnNonNullResult_ForAllUnM49Codes contains a huge
InlineData block; extract the UN M49 codes into a shared data provider and
switch the test to use MemberData (or ClassData) instead: create a static
IEnumerable<object[]> property or method (e.g. UnM49Codes or UnM49Data) that
yields each code string, update the Theory attribute to
[MemberData(nameof(UnM49Codes), MemberType = typeof(YourTestClassOrHelper))],
