Main changes

Reject invoices that have already been paid

The app now checks if an invoice has already been paid before sending. This does not work if the app has been restored and the payment is not in the database anymore.

Add information notice when the pay-to-open and swap-in features are disabled

Channel creation features involve on-chain operations and may be disabled when the mempool is congested. The app now degrades gracefully and properly informs the user, and also prevents using the swap-in feature.

Note that in that case the user is still able to receive using existing channels.
