fix(spp_aggregation,spp_metrics_services): eliminate N+1 queries and optimize fairness analysis

- Replace per-area child lookup loops with a single OR-chained domain search in
  aggregation_access.py and service_scope_resolver.py to avoid N+1 queries
- Refactor _analyze_many2one_dimension, _analyze_selection_dimension, and
  _analyze_boolean_dimension in fairness_service.py to use read_group instead of
  loading entire partner recordsets into memory

-OpenSPP Aggregation Engine
-==========================
-
-Provides a centralized aggregation service that unifies statistics computation
-across simulation, GIS API, and dashboards.
-
-Features
---------
-
-- **Unified Scopes**: Define targeting with CEL expressions, spatial polygons,
-  administrative areas, or explicit IDs
-- **Multi-dimensional Breakdown**: Group by configurable demographic dimensions
-  (gender, disability, area, age group)
-- **Privacy Protection**: K-anonymity with complementary suppression prevents
-  differencing attacks
-- **Access Control**: Aggregate-only access for researchers (no individual records)
-- **Distribution Statistics**: Gini coefficient, Lorenz curve, percentiles
-- **Fairness Analysis**: Parity analysis across demographic groups
