[Feature] Reduce clicks when commenting or zapping

[itstomekk]

Currently to zap you need to click once, then choose amount, then confirm. It could be one click with default amount (if specified in settings)

To broadcast, you also need to choose relays and then confirm broadcasting. Most users want just to click once

These could somehow go under advanced, ie. when you long click then you go with a longer flow, otherwise it oculd be simplified

I don't see a confirm when zapping after choosing amount. We can add an optional default zap amount for people that like that. I prefer always to choose the amount when zapping. When broadcasting a post, relays are already choosen by default, the popup serves more like a confirmation that you really want to broadcast, which I think is absolutely necessary to avoid mishaps. The list of relays can be collapsed by default to reduce complexity. @stackingsaunter design please
