Integrate e-signatures and email to court

[ekressmiller]

• Moved all e-signature questions to the end and merged that process with the email-to-court logic
• made refinements to the email to court process (though more polishing is still needed)
• edits to attachment blocks and docx templates to address a strange error where certain undefined variables were triggering questions on refresh of download screen despite "skip undefined: True" setting.
• minor changes for language consistency
