Add beta verbose progress controls

[zeolenon]

Summary

• Adds beta/experimental verbose progress support for CAS, defaulting off via config.
• Adds /cas_verbose [on|off|status] as a persisted runtime override and shows Verbose: on/off in /cas_status immediately after Plan mode.
• Emits reduced progress labels only (Working, Reasoning, Tool, Command, etc.) from app-server notifications, without exposing raw command text.
• Updates a single progress message where possible, falls back to replace-and-delete when edit fails, and cleans the progress message at turn completion.
• Uses the OpenClaw Telegram runtime API from plugin-runtime-deps for edit/delete when available, with raw API fallbacks.

Beta validation notes

• This was tested against the current beta CAS/OpenClaw Telegram flow.
• Verified /cas_verbose on, /cas_verbose off, edited progress updates, and final cleanup behavior in Telegram.
