Clio integration: pre-submission security hardeningSecurity

Deauthorize callback now requires a per-install shared secret in the URL path — the old unauthenticated endpoint is gone.
Webhook receiver now disables the affected install and returns 200 if the encrypted shared secret can't be decrypted, instead of looping on 500 retries.
Document download path enforces an explicit S3-only host allowlist on Clio's 303 redirect target, and re-issues the fetch anonymously without the Bearer token.

Five-country letter coverageFeature

Domestic letter delivery to the United States, United Kingdom, France, Germany, and Canada.
Each country routes through a licensed in-country print partner — the recipient sees their national postal service (USPS, Royal Mail, La Poste, Deutsche Post, Canada Post), not an international forwarder.
Tracked / signed-delivery services available where the carrier offers them.
