Add button to duplicate existing offers

[woodser]

This issue requests adding a button to duplicate existing offers so offers can be quickly created and customized.

See Bisq's code for reference, it should be the same: https://github.com/bisq-network/bisq/blob/e450c494bd68a901c4b85aa7ad45a0382b4fcf8a/desktop/src/main/java/bisq/desktop/main/portfolio/openoffer/OpenOffersView.java#L882C18-L882C47

I just noticed 'left click' with the mouse on Offer ID opens a menu: Create new offer like this...

Bisq has 2 options: Duplicate offer and Create offer (with shared maker fee)

Background information
By cloning an offer one creates a copy of the given offer with a new offer ID but using the same maker fee transaction ID.

This means there is no extra maker fee needed to get paid and the funds reserved for that offer can be re-used by the cloned offers. This reduces the liquidity requirements for market makers and allows them to post the same offer in different markets or with different payment methods.

As a consequence if one of the offers sharing the same maker fee transaction is taken all the other offers will get closed as well because the transaction output of that maker fee transaction is spent and would render the other offers invalid. 

This feature requires to use the same trade amount and security deposit and is only permitted for offers with different payment methods or currencies.

I think fractionally reserved offers are a stupid idea that shouldn't be implemented.

We wouldn't implement the shared trade fee thing. In Bisq the fee is paid to post the offer. In Haveno the fee is reserved when the offer is made but not paid until the offer is taken.

By "fractionally reserved offers" I mean using the same security deposit for multiple different offers. Imo that will lead to many failed take-attempts and grossly inflate how large the orderbook is in reality. The only people benefiting from this are traders with low amounts of Monero, meanwhile everyone else loses.

[woodser]

Yeah this issue is only to duplicate existing offers for convenience, but every offer still requires a separate trade fee and security deposit.

But we can already "create new offer like this"?

Yes, that's possible. For example, I have a EUR/SEPA trade for €42 online right now, which I duplicated.
