v2: In-app support chat with Telegram notifications (REVIEW — not deployed)

Backend:
- New models: SupportThread, SupportMessage (models/support.py)
- Support router: user thread/messages, admin threads/reply, Telegram outbound
- Context auto-attached: active program, points, gate status, last workout
- Rate limited: 10 messages/user/day
- Admin auth: username == 'scot' check
- Telegram: fire-and-forget sendMessage via @AureusGoldBot, never blocks
- config.py: added telegram_bot_token, telegram_chat_id

Frontend:
- Support.jsx: chat-style thread, send messages, confirmation, auto-scroll
- SupportAdmin.jsx: thread list with unread badges, thread detail with context sidebar, reply
- App.jsx: floating '?' help button with unread badge (polls every 60s), routes
- api.js: support endpoints (user + admin)

Config:
- docker-compose.yml: TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID env vars

NOT DEPLOYED — requires Telegram env vars in Coolify
