feat: enhance team provisioning and activity timeline for improved messaging

- Updated TeamProvisioningService to mirror provisioning narration into the live cache, allowing visibility in Messages/Activity.
- Modified TeamDetailView to include current lead session ID for better context in team interactions.
- Enhanced ActivityTimeline to suppress reconnect boundaries based on current lead session ID, improving session clarity.
- Adjusted MessageComposer to clarify provisioning status in UI messages and placeholders, enhancing user awareness during team launches.
