feat: Add documentation and task tracking for Sprints 508 to 514 in Ops & Offline

- Created detailed markdown files for Sprints 508 (Ops Offline Kit), 509 (Samples), 510 (AirGap), 511 (Api), 512 (Bench), 513 (Provenance), and 514 (Sovereign Crypto Enablement) outlining tasks, dependencies, and owners.
- Introduced a comprehensive Reachability Evidence Delivery Guide to streamline the reachability signal process.
- Implemented unit tests for Advisory AI to block known injection patterns and redact secrets.
- Added AuthoritySenderConstraintHelper to manage sender constraints in OpenIddict transactions.
