[Improve] Identify custom automation runs in Telegram

[roomote-roomote]

​Opened on behalf of @daniel-lxs. Follow up by mentioning @roomote-roomote, in the web UI, or in Telegram.

What changed

• Identify Telegram custom automation kickoffs with the automation name and an explicit running status.
• Preserve automation identity on final Fast-only and delegated-task reports.
• Keep Telegram's existing Open in Roomote Session footer instead of copying Slack Block Kit controls.

Why this change was made

Telegram automation messages previously looked like ordinary Fast Session replies, making it unclear that they came from a configured automation. This brings the important identity and live-Session affordance into the Telegram presentation while preserving provider conventions.

Impact

Telegram users can distinguish automation runs at kickoff and in final reports, and can open the corresponding live Session through the existing footer link. Ordinary non-automation Telegram replies are unchanged. Focused SDK tests, SDK typechecking, linting, formatting, and the repository pre-push checks pass.
