feat(auth): add trusted-device 30-day 2FA skip (backend)

Adds a "trust this device" option to the 2FA challenge: on success, mints a
random token (only its SHA-256 hash is stored), sets it as a new httpOnly,
Secure, SameSite=Strict cookie, and records a TrustedDevice row. AuthController
checks that cookie for the exact signing-in user before gating on 2FA -- a
mismatched user, expired, or revoked device falls through to the normal 2FA
prompt, never errors. TwoFactorController also exposes list/revoke/revoke-all
endpoints for managing trusted devices, scoped to the owning user.

Schema added via the existing raw-SQL reconciler (SQLite + MySQL dialects),
not EF migrations, matching this repo's established pattern.
