front: Update Region object properties in map component.

Refined the region object structure in MapComponent by updating 'hasSubregions'
property with actual data from the 'newRegion' and altering the TODO comments
to reflect the shift in scope for fetching region info and adding it to the
region object.

Issue: #186
