Add content about silent payments

[mouxdesign]

Describe your content request
Would like to suggest adding content about silent payments to the guide.

Link to the page
Currently there is no page in the guide that specifically covers silent payments. There is a mention of silent payments in the How it works section.

Why would you like to change the content?
This could go in the How it works section and would fall under privacy. Open to suggestions on the location.

Suggestions
The content itself would include:

• Introduction
• Use cases
• Send flow
• Receive flow

Additional context
A draft of a write up has been created on this topic here.
We also have a Learning Bitcoin & Design call about this in February. After the learning call it would be great to flesh out the content more once we have a deeper understanding of it. The move to screen designs for the user flows.

For those considering listening to the call, the AI-generated transcript is accessible via btctranscripts. You can review and edit the transcript in real-time, enhancing its accuracy and clarity for everyone's benefit.
