- credential_id can exceed the unique-index key length; store it in TEXT and
enforce uniqueness on an auto-derived sha256 hash column (lookups use the hash).
- Disabling 2FA now also deletes the user's security keys + backup codes, so
re-enrolling starts clean and old factors never silently revive.

Persist the updated PublicKeyCredentialSource (not just the sign_count column)
so the next assertion validates against the latest counter — keeping the
library's cloned-authenticator / counter-rollback detection effective.

WebauthnService builds creation/request options (rpId = active domain, ES256/RS256,
attestation none, exclude/allow lists) via web-auth/webauthn-lib v5, stores the
challenge in the session, and verifies attestation/assertion responses (allowed
origin = https://<rpId>, sign-count tracked). Option building + serialization are
unit-tested; the cryptographic verify path is browser-verified on a domain host.

WebAuthn is offered only with an active domain (the rpId) over HTTPS; bare-IP/HTTP
returns false so a ceremony never runs with an invalid IP rpId.
