UX improvements driven by live testing: - setMyCommands populates Telegram's '/' picker with all commands and descriptions, so the operator gets autocomplete instead of guessing syntax. - /start replies with an inline keyboard ([📒 Accounts] [📡 How to Pair] [❓ Help]) — quick navigation without typing. - /accounts emits one message per account with [📂 Groups] [🗑 Unpair] inline buttons. Tapping triggers a callback (no typed labels needed). - New callbacks module wires the buttons. Unpair shows a confirm/cancel prompt before acting. /pair still requires a typed label since the value is operator-defined content rather than a selection from existing data.
