Dju/new lender invest menu

[djudjuu]

whats done

• display borrowers in a dediced InvestmentOptionCard
  • (basic styling only)
  • hardcoded loan request terms
  • three different cards: active loan, requested loan, no loan request
• new table to manage borrower/investor relations
• actions to update the table, triggered by a button
  • asking confirmation when removing withdrawal
  • basic tests
• dummy explainer as to what happens when withdrawing

NOTE/QUESTIONS

currently we dont refresh the user data, user-data only changes upon page refresh, which is a bit weird when you have hit a button. currently we only fetch the user data in the session callback. To make it more reactive, we could probably write a new Action.GetUserData and use it with useEffect() inside the component. Would that be the correct way to do it?

TODOs:

• [ ] squash migrations
• [ ] add style to make the card look better
• [ ] add spacing between cards & between explainer

closed in favor of #219 where this view is integrated...the issue that user data is not refreshed remains
