Add indication that BSQ transactions are not up to date

[ripcurlx]

Fixes #2303.

ACK

I have tested and it works, but I still think it would be better with a separate service for the sync handling to not pollute the setup class.

I think it would be better to make a separate BSQSyncService or something like that, it feels wrong to add this to the DaoSetup.

I would prefer to not use DaoSetup for that but DaoFacade (or some custom class). I will have a look soon into it to make a more concrete sugestion.

NACK

Yes, I also wasn't quite happy to put it in this place, I just though to make it consistent how it is handled with the btcInfo WalletSetup right now:

bisq/core/src/main/java/bisq/core/app/BisqSetup.java

Lines 341 to 348 in 8cdc759

	// Wallet
	public StringProperty getBtcInfo() {
	return walletAppSetup.getBtcInfo();
	}
	public DoubleProperty getBtcSyncProgress() {
	return walletAppSetup.getBtcSyncProgress();
	}

bisq/core/src/main/java/bisq/core/app/WalletAppSetup.java

Line 68 in 8cdc759

private final StringProperty btcInfo = new SimpleStringProperty(Res.get("mainView.footer.btcInfo.initializing"));

How do we differentiation between a Facade and a Service atm in Bisq?
I'll have a look to find a better place for this presentation logic. I might change the implementation of the btcInfo/btcSyncProgress on the way as well.

I moved the code into the DaoPresentation class which I created already for another DAO related PR.
