feat: initial JavaScript port of store-scraper-bot

Node.js 20+ ESM port mirroring Java/Go implementations.

- 13 Telegram commands matching Java identifiers
- MongoDB schema parity (common, group, apple_app, google_app collections)
- Apple/Google scrapers calling store-scraper.vercel.app with 10-min cache
- Daily 7am Vietnam-time cron with weekend-silent mode
- HTML table renderer matching Java/Go output
- Docker + Compose (prod and dev)

Untested end-to-end against live Telegram or upstream API.
