dApp - adapt UDC withdrawal information to timestamps

[weilbith]

Description

We have a visual component that informs the user that a UDC withdrawal was planned and is waiting to become finally withdrawn. The included counter was based on block numbers. Due to this, the dApp is actually not even "compiling" anymore, as the new SDK version does not provide a block property for planned withdrawal events anymore.
First this needs to be adapted from a target block number to a target timestamp. The challenge is now how to adapt the visual part. Before, the new block event was causing the reactive update that result into a new "remaining block numbers" and thereby a countdown. As there is no such event for this use-case anymore as it is purely time based, we need to find an alternative.
One would be to use a countdown of the seconds. This is very similar to the old visuals, but not very nice. An alternative would be to render the actual date when the withdraw becomes possible.
