feat: Enhance session processing and metrics

- Updated session processing commands in documentation for clarity.
- Removed transcript content fetching from session processing, allowing on-demand retrieval.
- Improved session metrics calculations and added new metrics for dashboard.
- Refactored processing scheduler to handle sessions in parallel with concurrency limits.
- Added manual trigger API for processing unprocessed sessions with admin checks.
- Implemented scripts for fetching and parsing transcripts, checking transcript content, and testing processing status.
- Updated Prisma schema to enforce default values for processed sessions.
- Added error handling and logging improvements throughout the processing workflow.
