chamikaJ bdc3050a5e feat(database): add performance indexes for optimized task queries
- Introduced a new SQL migration file to create various performance indexes on tasks, task_assignees, task_phase, and related tables.
- These indexes aim to enhance query performance for task filtering, status joins, assignees lookup, and other operations, improving overall application efficiency.
