Implement ExpandableWidget

🚀 Feature Proposal

As a developer I want to have an ExpandableWidget component which expands a widget component to an expanded view.

Motivation

The ExpandableWidget is a core UI element of Akamu which is frequently used in various screens. Thus, as a developer, I want to re-use the predefined component and to just pass the shrunk and expanded views to it, instead of implementing it every time.

Technical Details

Example

DuelWidget in DashboardScreen:

User clicks on duel widget card which leads to opening/expanding of the widget to a expanded version which contains more detail info / the duel list itself
