Add WebAuthn integration, reCAPTCHA support, and new tests

- Integrate WebAuthn library for passkey authentication workflows, including assertion verification and improved error handling. - Add support for reCAPTCHA token validation across multiple endpoints for enhanced security. - Extend OpenAPI schema to document new fields and restructured payloads. - Add unit tests for WebAuthn flows, permission initialization, and route validation to ensure robustness and accuracy.
