fix: restore security hardening compatibility and validation

Restore authorized rule reveal, explicit full HTTP capture and retention, video task business fields, and valid payment URLs. Add opt-in credential preservation for trusted recovery, fix frontend type contracts and async races, and eliminate PostgreSQL test fixture resource leaks. Document audit coverage and successful fmt and CI-scoped Clippy checks.
