wallet: Display incoming transaction in Deposit modal

[peterzen]

This PR implements deposit transaction detection.

Closes #2662

This diff only fixes the main issue of address reuse if the deposit modal remains open when the transaction is received. I think generally the user will not keep it open.

Maybe you can do something like this: 296ae25

Simpler approach in #2690. I'm not trying to steamroll you, @peterzen.

Address reuse and display of incoming deposits are separate issues, and displaying incoming deposits is largely resolved by recent txs ui.

The confirmation in the modal would still be useful, it's standard pattern in wallets/dexes. How about rigging this UI onto #2690?
