## Description

Create the Telegram bot backend for commands, inline keyboards, callback queries, deep links, and outbound notifications.

## Details

Support start/help/link/status/request/offer/payment/dispute/settings basics. Use short opaque IDs or signed tokens for callback payloads. Process incoming updates idempotently with rate limits. Respect notification preferences, quiet/error states, failed delivery, blocked bot, and retry observability.
