Redesign: Start/Stop buttons, locked settings, queue countdown, wb2 logo

- Replace tumbler with Start/Stop buttons (green/red)
- Lock settings form with <fieldset disabled> when auto-reply active
- Clear queue + reset fetch timer on settings save
- Show 'Очередь подгрузится через X сек.' countdown in queue section
- API /status returns next_fetch_seconds, queue_len, auto_reply_enabled
- Login: price 15₽/день, up to 144 replies/day, wb2 logo, promo panel 25% width
- Replace wb.png → wb2.png across all templates
