refactor: extract bot command catalog as single source of truth

src/bot/commands/index.js owns the canonical catalog (name, description,
adminOnly, build factory). bot.js builds dispatch from it; future menu
registration reads it. Drops the 14 explicit factory imports + the inline
/info handler from bot.js. Prevents the dispatch-vs-menu drift that bit
us with /setdayswarning (commit 0131206 → 49726f1 backfill).

 - Upstash Redis schema mirrors the Java/Go Mongo layout: keys `admin`,

+- Command set defined in `src/bot/commands/index.js` (single source of truth — catalog drives both dispatch and the Telegram menu). Admin-only commands are hidden from the default menu and shown only in per-admin chat scope.
 - HTML parse mode; weekend-silent daily report; configurable upstream cache (default 10 min).
 - Per-group warning threshold override via `/setdayswarning` (falls back to `NUM_DAYS_WARNING_NOT_UPDATED` env default).
 - Inlined `app-store-scraper` + `google-play-scraper` (no external scraper service).
