fix: Recover in-memory dispatch queues from DB on server startup

Both phaseQueue and taskQueue are in-memory Maps lost on restart. Now
the orchestrator's start() method scans active initiatives and:
- Re-queues approved phases into the phase dispatch queue
- Re-queues pending tasks for in_progress phases into the task dispatch queue
- Triggers a dispatch cycle if anything was recovered

This fixes stuck phases/tasks after server restarts.
