Generate and attach PDFs corresponding to the electronic signatures

[ryanhofdotgov]

As a user, I want to be able to download and archive a record ("receipt") of the waivers and releases I electronically sign.

As a system owner, I want to be compliant with the federal ESIGN Act and I want eQIP reviewers to accept the applications eApp submits to it.

Per discussion with Chris, Drew, Michael – online display of waiver text can take a different visual appearance/formatting from the archival PDF, but the text of the agreement must match exactly.

eQIP re-authenticates users with their password before permitting to e-sign – exploring that in #375. Implementing this feature ahead of #375, as initial users will be authenticated with CAC/PIV.
