[VDG][Trivial] Simplify text of Preview Transaction dialog

[yahiheb]

The Transaction Preview dialog (when sending) is full of text and not user friendly imo.

This is a small PR with minimal effort to simplify the text and make the dialog less cluttered.

Just a comment but not a suggestion of changes for this PR, this field and the previous one (so receiver label + address) could be merged into one, it would declutter the screen and help for global understanding.

That makes sense to me. It can be done in another PR.

I am wondering why aren't the titles capitalized?

It looked a bit better like this, but at the end it was just a choice.

To prevent confusion, I would make it clear that the fee gets added to the amount, not deducted/part of it

so additional fee

Where does this confusion come from?
If the user typed an amount to be sent, there is no reason to think it will be changed arbitrarily.

"A fee is the cost of something, or the amount of money charged."
In our context it means the cost of the transaction, and this screen shows the details of the transaction, thus saying fee should be enough.
