[Payjoin] SendPayjoin Issues

[i5hi]

For a payjoin send:

• when a payjoin address is pasted the UI should mention that the transaction is a payjoin on the build tx page
• the build process should be separated from the confirm process and we should have a screen to confirm the details
• after confirm there should be a status page for the payjoin (similar to swaps) - there is an option to exit and go to the transaction detail page or go back home
• there should be a toast that notifies the user when a payjoin broadcasts

• Separate uri & address copy in receive page (feat: add copying of address only to receive with payjoin #376)
• Make historic transfer amounts accurate by taking the difference of sent and received
