Adds Cloud Signature Consortium (CSC) integration for AES/QES signing
against a configured TSP. v1 ships as instance-wide configuration via
environment variables, with per-envelope signature level selection,
license gating, and an OAuth-driven signing flow (capture + FIFO
signers, SAD session, blocking/in-progress recipient pages).
Includes signature level compatibility checks (role, signing order,
dictate next signer), envelope mutability assertions, Prisma migration
for signature level and CSC tables, and docs for the new signing
certificate options.
## 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
## Description
Replace the PDF renderer with an custom image renderer.
This allows us to remove the "react-pdf" dependency and allows us to use
a virtual list to improve performance.
