feat: prefill typed signature with user's full name (#2324)

Add fullName prop to signature pad components to automatically populate
typed signature
field with signer's name. Updates signature dialog, type component, and
all signing forms
across embed, document, template, and envelope flows to pass through the
user's full
name for better user experience.
