Fix WebAuthn login: username pre-fill and policy check

- webauthn.js: read #username value before calling
  mciasWebAuthnLogin so non-discoverable keys work when
  a username is typed (previously always passed empty string,
  forcing discoverable/resident-key flow only)

- handleWebAuthnLoginFinish: evaluate auth:login policy after
  credential verification, mirroring the gate in handleLogin;
  returns 403 on deny so policy rules apply equally to both
  password and passkey authentication paths

Security: policy is checked post-verification so 403 vs 401
distinguishes a policy restriction from a bad credential without
leaking account existence. No service context is sent (WebAuthn
login carries no service_name/tags), so per-service deny rules
don't fire on passkey login; account-level deny rules do.

+## WebAuthn / Passkey Configuration
+
+WebAuthn enables passwordless passkey login and hardware security key 2FA.
+It is **disabled by default** — to enable it, add a `[webauthn]` section to
+`mcias.toml` with the relying party ID and origin.
+
+### Enable WebAuthn
+
+Add to `/srv/mcias/mcias.toml`:
+
+```toml
+[webauthn]
+rp_id        = "auth.example.com"
+rp_origin    = "https://auth.example.com"
+display_name = "MCIAS"
+```
+
+- **`rp_id`** — The domain name (no scheme or port). Must match the domain
+  users see in their browser address bar.
+- **`rp_origin`** — The full HTTPS origin. Include the port if non-standard
+  (e.g., `https://localhost:8443` for development).
+- **`display_name`** — Shown to users during browser passkey prompts. Defaults
+  to "MCIAS" if omitted.
+
+Restart the server after changing the config:
+
+```sh
+systemctl restart mcias
+```
+
+Once enabled, the **Passkeys** section appears on the user's Profile page
+(self-service enrollment) and on the admin Account Detail page (credential
+management).
+
+### Passkey enrollment
+
+Passkey enrollment is self-service only. Users add passkeys from their
+**Profile → Passkeys** section. Admins can view and remove passkeys from
+the Account Detail page but cannot enroll on behalf of users (passkey
+registration requires the authenticator device to be present).
+
+### Disable WebAuthn
+
+Remove or comment out the `[webauthn]` section and restart. Existing
+credentials remain in the database but are unused. Passkey UI sections
+will be hidden.
+
+### Remove all passkeys for an account (break-glass)
+
+```sh
+mciasdb --config /srv/mcias/mcias.toml account reset-webauthn --id <UUID>
+```
+
+---
+
+## TOTP Two-Factor Authentication
+
+TOTP enrollment is self-service via the **Profile → Two-Factor Authentication**
+section. Users enter their current password to begin enrollment, scan the QR
+code with an authenticator app, and confirm with a 6-digit code.
+
+### Admin: Remove TOTP for an account
+
+From the web UI: navigate to the account's detail page and click **Remove**
+next to the TOTP status.
+
+From the CLI:
+
+```sh
+mciasdb --config /srv/mcias/mcias.toml account reset-totp --id <UUID>
+```
+
+This clears the TOTP secret and disables the 2FA requirement. The user can
+re-enroll from their Profile page.
