feat: add nav and paging, and improve formatting

- rename Transaction to Offer
- added a Config panel
- restructure main page layout to not use grid
- structure app to have effectively panels controlled by top nav

minor UI items:
- add a button type for menus (TODO: show the selection correctly)
- make ListItems support horizontal lists
- align action buttons in ListCard
