feat: Implement AccountSection
- Multiple accounts per user can be collapsed into a single top card
with ghost cards beneath it with a button to expand the exact number
of accounts that there are
- The button for collapsing is in the top right and the button for
expanding is at the bottom of the ghost cards
- The view of the accounts can be reordered, using drag & drop and by
using the buttons for up and down when in Edit mode. Upon finishing with
editing the reorder, you can click the Done button and the edit mode will
be disabled. The order is kept in localStorage to be persistent for users
- When there aren't any accounts, there is a text saying that and the
buttons for collapsing/expanding and editing are disabled/not shown
