feat(ledger-browser): refactor home page

- Remove status apps, its functionality has been moved to the home page.
- Add status components for persistence apps.
- Add home page that contains cards for each configured app. Clicking on it
  naviagtes to specific app, clicking on Status button shows status component.
- Remove app drawer, replace it with a button that navigates to root path
  (i.e. the home app, navigation between apps is handled here).
- Remove all the remaining dead and legacy code, apply small structure upgrades.
- Since this PR removes all old code, and all the current code was written by
  me and Tomasz, I've also removed previous inactive package contributors.

Depends on hyperledger-cacti#3320
