feat: TTLock — add Учетная запись + Пароль fields for OAuth

Per Sciener docs: OAuth requires TTHotel account credentials (Учетная запись + Пароль)
separate from developer app client_id/client_secret.

- Migration 055: add ttlock_username, ttlock_password columns
- Backend: store and pass new fields to agent
- UI: add input fields matching TTHotel PMS integration page
- Agent: getAccessToken() uses ttlockUsername/ttlockPassword when provided
