Improve the send flow

[almaraz97]

Friction- the current flow involves 3 different pages with a minimum of 5 clicks in the simplest possible case. Abstracting or at least reducing the mental load of filling this out is important.

Clarity- there isn't much explanation regarding the metadata fields, why to use the different payment terms, having an overview of the process, and at the end having a summary regarding the payment agreement.

Familiarity- the payment term section is not a standard way of interacting with options (a row boxes with select buttons and fields that appear onClick). Improve the design of this or abstract it.

Easy extensibility- there should be an easy way to incorporate new payment terms to the UI

Aesthetic- improve the approachability and enjoyability of sending a Nota. This could be box sizing, color scheme, animations, etc
