Now after /start, manager sees a bottom keyboard (4 rows) for fast access:
Row 1: 🤖 Подбор техники | 📐 Новый замер ← WebApp
Row 2: 👥 Мои клиенты | 🏠 Кабинет ← WebApp
Row 3: ℹ️ Что умеет бот? | 📞 Куратор ← text
Row 4: 📋 Чек-лист встречи ← text
WebApp buttons jump straight to a MiniApp screen via ?go=<podbor|measure|clients>;
app.js parses ?go on load and pre-sets location.hash so the right module mounts.
Added /menu (re-show keyboard) and /hide (remove). Text buttons trigger
in-chat info responses (bot description, contact, meeting checklist).
