🎨 Fix 5 Whys agent layout to match other agent templates

- Move 'How it works' widget to sidebar position (below wallet card)
- Add wallet card component to chat template layout
- Use consistent grid layout: main chat widget + sidebar
- Maintains chat functionality while improving UI consistency
- Now matches standard agent template structure

Fixes layout inconsistency where 'How it works' was at bottom instead of sidebar.
