Khalim Conn-Kowlessar c3691d9af2 refactor(property-baseline): rename baseline → property_baseline aggregate (PR #1139 review)
Wholesale rename of the Baseline aggregate to PropertyBaseline for clarity /
to disambiguate from baselines that appear elsewhere in Modelling. Scoped to
this aggregate only — the distinct Rebaselining term (rebaseline_reason,
StubRebaseliner, RebaselineNotImplemented) is deliberately untouched.

- domain/baseline → domain/property_baseline; BaselinePerformance →
  PropertyBaselinePerformance.
- repositories/baseline → repositories/property_baseline; BaselineRepository
  / BaselinePostgresRepository → PropertyBaseline*.
- orchestration/baseline_orchestrator.py → property_baseline_orchestrator.py;
  BaselineOrchestrator → PropertyBaselineOrchestrator. BaselineStage →
  PropertyBaselineStage.
- infrastructure/postgres: baseline_performance_table.py →
  property_baseline_performance_table.py; table `baseline_performance` →
  `property_baseline_performance`; Model renamed.
- UnitOfWork attribute `.baseline` → `.property_baseline`.
- Docs: ADR-0004 references + migration doc (renamed to
  property-baseline-performance-table.md) updated.

CONTEXT.md glossary term ("Baseline Performance") left as-is pending a
ubiquitous-language call (raised on the PR). 123 tests pass; pyright strict
clean (only the unrelated pre-existing moto import errors remain).

"""In-memory fakes for orchestrator unit tests (no DB, no network).
A `FakeUnitOfWork` exposes dict-backed fake repos and records commits, so a
test can drive an orchestrator and then assert what was persisted and that the
batch committed exactly once (ADR-0012)."""
