feat(migration): add index on created_at for audit_logs

Browse Source 
Introduced an index on the created_at column of the audit_logs table to optimize the daily retention sweep, improving performance by reducing the need for full table scans during deletions. This change enhances the efficiency of the retention process, particularly for tenants with high RBAC traffic. The corresponding down migration includes the removal of this index.
