Enhanced the DXCC data update interface by adding a spinner, disabling the button during updates, and providing immediate status feedback. Polling intervals were reduced for more responsive updates, and error handling was improved to reset UI elements on persistent errors.
Blue Solid = Add something, activate something, or perform any other primary action.
Blue Outline = Edit, change or update something.
Red = Delete something or make an irreversable change.
Grey = Deactivate something.
Yellow = Reset something or clear a field.
Green = Retained for search.
Added icons where it made sense to do so.
