Make anonymous zaps explicit

[Giszmo]

I zapped many times now without it actually zapping. The way this happens is that I click on "Login" under an article (zapthreads) and then as I see my face down there I click on the ⚡ and it "doesn't work". I then have to awkwardly take credit in a reply for a zap nobody sees unless the recipient acknowledges it.

Please make this less prone to happen, ideally by some confirmation dialog if no nostr account is present as I suspect that most people want credit for their zaps. At the very least make it a zap with an ephemeral nostr key to have some sort of receipt.
