⚡ Bolt: Resolve N+1 query problem in EscalationEngine

[RohanExploit]

💡 What: Added joinedload(Grievance.jurisdiction) to the SQLAlchemy query in _get_grievances_for_evaluation.
🎯 Why: Previously, evaluating grievances in a loop in evaluate_and_escalate_grievances caused an N+1 query problem because _should_escalate accesses grievance.jurisdiction.level, which triggers an individual SELECT statement for every grievance evaluated.
📊 Impact: Reduces database queries from O(N) to O(1) for this specific escalation check, improving the scalability of the background task as the number of grievances increases.
🔬 Measurement: Verify by ensuring that joinedload successfully eager-loads the related jurisdiction models, preventing the emission of multiple lazy loading SELECT queries in the database logs during SLA evaluation.

Summary by cubic

Eager-load Grievance.jurisdiction in _get_grievances_for_evaluation using joinedload to remove the N+1 query triggered by grievance.jurisdiction.level during escalation checks. This reduces DB queries from O(N) to O(1) and speeds up SLA evaluation in the background job.
