Add 'Detect and Join Conversation' button to Web UI and CLI

- Added /autonomous/join-conversation API endpoint in api.py
- Added 'Detect and Join Conversation' button to Web UI under Autonomous Actions
- Added 'autonomous join-conversation' command to CLI tool (miku-cli.py)
- Updated miku_detect_and_join_conversation_for_server to support force=True parameter
- When force=True: skips time limit, activity checks, and random chance
- Force mode uses last 10 user messages regardless of age
- Manual triggers via Web UI/CLI now work even with old messages
