fix: hide name/email in embed signing when provided via prop (#2600)

## Description

When signing via embed, recipient name and email provided through the
embed context were ignored if the DB recipient record had empty values.

This fix adds:
- the signing context's fullName and email as fallbacks in the recipient
payload
- keeps the form in sync with values instead of defaultValues
- ensures the override payload is sent even when the form is hidden
