Please add auto-stake function

[Bambarello]

Please add the auto-stake function to the pullup wallet, for example

1. select the node for stake
2. provide wallet password
3. checkbox-auto -> switched on
4. select the SERO threshold to be staked every automatic turn
5. if all is ok -> the wallet shall atomatically check the balance (for example every day) and in case the available balance increased after shares unblocked -> re-purchase the shares automatically using the rules above
