feat(tgbot): register usage, inbound, restart and clearall in the bot command menu

The Telegram command menu listed only start/help/status/id although usage, inbound and restart were already handled, and resetting all traffic was reachable only through inline keyboards. Register all handled commands with localized descriptions and add an admin-gated /clearall command that reuses the existing reset-all confirmation keyboard, so nothing destructive runs without an explicit confirm.

Closes #5307
