feat(migrations): add initial migration setup and performance indexes
- Introduced .pgmrc.json and migrate.json for node-pg-migrate configuration. - Added multiple migration files to create performance indexes for tasks and related entities. - Implemented functions for optimized task sorting and manual progress tracking. - Updated package.json to include migration scripts and dependencies for node-pg-migrate. - Created README.md for migration guidelines and best practices.
