feat: Implement structured message parsing and display in MessageViewer component

- Added MessageViewer component to display parsed messages in a chat-like format.
- Introduced new Message table in the database to store individual messages with timestamps, roles, and content.
- Updated Session model to include a relation to parsed messages.
- Created transcript parsing logic to convert raw transcripts into structured messages.
- Enhanced processing scheduler to handle sessions with parsed messages.
- Updated API endpoints to return parsed messages alongside session details.
- Added manual trigger commands for session refresh, transcript parsing, and processing.
- Improved user experience with color-coded message roles and timestamps in the UI.
- Documented the new scheduler workflow and transcript parsing implementation.
