feat: Implement session processing and refresh schedulers

- Added processingScheduler.js and processingScheduler.ts to handle session transcript processing using OpenAI API.
- Implemented a new scheduler (scheduler.js and schedulers.ts) for refreshing sessions every 15 minutes.
- Updated Prisma migrations to add new fields for processed sessions, including questions, sentimentCategory, and summary.
- Created scripts (process_sessions.mjs and process_sessions.ts) for manual processing of unprocessed sessions.
- Enhanced server.js and server.mjs to initialize schedulers on server start.
