Add Telegram Mini App (web UI + API server + localtunnel)

- server.py: aiohttp API serving webapp/ and REST endpoints using existing db.py
- start.py: orchestrator that loads token, starts server + localtunnel + bot
- webapp/: Mini App frontend (Log, History, Stats) with Telegram-native theming
- bot.py: added Mini App menu button and inline button on /start
- flake.nix: added aiohttp + localtunnel, nix run now uses start.py
