This PR implements the **"Lock to Single Conversation"** option for
Telegram inboxes, bringing it to parity with WhatsApp, SMS, and other
channels.
- When **enabled**: resolved conversations can be reopened (single
thread).
- When **disabled**: new messages from a resolved conversation create a
**new conversation**.
- Added **agent name display** in outgoing Telegram messages (formatted
as `Agent Name: message`).
- Updated frontend to display agent name above messages in the dashboard
(consistent with WhatsApp behavior).
This fixes [#8046](https://github.com/chatwoot/chatwoot/issues/8046).
