refactor(telegram-bot): split 2097-LOC god-file into rugmunchbot package (P3B.3)

Move app/telegram_bot/bot.py verbatim to app/telegram_bot/rugmunchbot/bot.py
with a thin RugMunchBot class wrapper for the orchestrator and a
HANDLER_REGISTRY for declarative command wiring.

The legacy app/telegram_bot/bot.py becomes a 49-line re-export shim.
All 58 command handlers and helpers remain importable. Routes unchanged.
