Even with authenticatorAttachment=cross-platform, Bitwarden's extension
intercepted navigator.credentials.create and offered to save a passkey. Add the
WebAuthn L3 'hints: [security-key]' to both registration and assertion options;
browsers and passkey managers that honor hints step aside and let the hardware
key prompt through. Injected into the client payload only (the session copy used
for server validation is unchanged).

Registration set no authenticatorSelection, so the browser offered the
passkey-manager 'save passkey' flow (Bitwarden) instead of prompting for the
YubiKey. Now request a cross-platform, non-resident, presence-only credential:
authenticatorAttachment=cross-platform (roaming key, not a platform/manager
passkey), residentKey=discouraged (non-discoverable second factor — what keeps
passkey managers out), userVerification=discouraged (single touch, no PIN).
Login assertion also uses discouraged so it is: insert key, one tap, done.

WebauthnService::available() keyed on request()->isSecure(), which is false in
external-proxy mode (the forwarded https scheme isn't trusted without
TRUSTED_PROXY_CIDR) — so hardware keys were locked even though the panel runs
over HTTPS on the domain. Gate on being reached via the active domain instead
(always HTTPS through the front door); the bare-IP recovery host stays locked.
A core security feature no longer depends on an optional proxy setting.

- Swap the strict counter checker for a zero-tolerant one so platform
authenticators / synced passkeys (which always report counter 0) can assert,
while non-zero counters still must strictly increase (clone detection).
- Guard registration (options + register) and the UI on hasTwoFactorEnabled, so a
key is never created against a disabled/reset second factor.

- 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.
