fix: review email — hotel-branded header, proper first name, 30d guard, brand color

- Email no longer shows HotelSync branding, shows hotel name instead
- Greeting uses second word of guest_name as first name (Фамилия Имя format)
- Footer link changed to hotelsync.ru
- Brand color from hotel settings applied to email button/header
- Job: only process bookings checked out within last 30 days (prevents bulk send on first activation)
