docs: correct SAP calculator path in CONTEXT (domain/sap → domain/sap10_calculator)

Browse source 
Factual staleness fix flagged in the handover; the calculator lives in
domain/sap10_calculator/calculator.py. Glossary term 'Baseline Performance'
deliberately left unchanged (concept vs PropertyBaselinePerformance class).

**SAP10 Calculation**:
The process that runs the deterministic SAP 10.2 (14-03-2025 amendment) worksheet over a Property's EpcPropertyData and emits **Calculated SAP10 Performance**. Implemented by the `Sap10Calculator` service class in `domain/sap/`. Reads cert fabric/heating/geometry fields, applies the RdSAP 10 (10-06-2025) cert→input mapping, executes the 12-month heat balance per SAP 10.2 §§1-14, looks up boiler/heat-pump performance in the **PCDB** when the cert lodges a product index, and returns a `SapResult` carrying the five Calculated SAP10 Performance quantities plus a monthly breakdown and worksheet-line audit trail. Distinct from **Rebaselining**, which is ML-based. ADR-0009 originally targeted SAP 10.3 (13-01-2026); ADR-0010 retargets to SAP 10.2 (14-03-2025) until the cert corpus migrates.

*deliberately* left un-renamed — treat "Baseline Performance" as the spoken concept and
`PropertyBaselinePerformance` as its class. If you want them aligned, rename the term to
"Property Baseline Performance" across CONTEXT + ADR prose (a quick, mechanical change).
- **CONTEXT.md ≈line 105** says the calculator lives in `domain/sap/` — that's **stale**;
it's `domain/sap10_calculator/calculator.py`. Safe to correct.
