Make migrations idempotent and add missing tables

- Make all pending migrations idempotent (safe to re-run)
- Disable decouple_projects_from_rounds migration (schema not changed)
- Add ProjectTag table for AI tagging
- Add AssignmentJob table for AI assignment progress

On server deployment, run: npx prisma migrate deploy
