[Woo POS][Cash & Receipts] Update customer with email and use action to send it

[kidinov]

Closes: #13031

Description

The PR adds calling of the two endpoints:

• One to update an email of the order
• The second to call action that uses that email to send order details

Testing information

• Use flipper to monitor network request
• Use the 9.5.0 beta version of the Woo Core
• POS -> Make an order
• Receipts
• Send a receipt to an email you use
• Validate network calls in flipper

• I have considered if this change warrants release notes and have added them to RELEASE-NOTES.txt if necessary. Use the "[Internal]" label for non-user-facing changes.
