Fixed DataMap → Datamap Property Naming

ARCtrl renamed the DataMap property to Datamap. Updated all references across:

• SwateControlService.ts: Updated imports and property access
• SwateView.vue: Updated save handler for datamap processing
• ArcTreeView.vue: Updated add/delete datamap operations

Fixed Format Field Type Mismatch Bug

Root Cause: The format field of dataContext is sent as a boolean value, but ARCtrl's JSON deserializer expects it to be a string or omitted entirely. This caused JsonController.Datamap.fromJsonString() to fail

• The format field type issue should ideally be fixed upstream to send strings instead of booleans
