- Added logic to enable the reporting button based on chat state and message presence.
- Introduced a computed property to determine if the chat can be reported.
- Updated the reporting method to accommodate the last partner in case the current partner is unavailable.
- Improved handling of partner details in the reporting payload for better accuracy.
