Re-runs of a First Run batch re-save a property's data; that must replace,
not duplicate (ADR-0012 idempotent batch writes).
- `EpcPostgresRepository.save` deletes the property's existing EPC graph
(parent + all child tables, floor-dims via their building parts) before
inserting, when a `property_id` is given. Anonymous saves still insert.
- `BaselinePostgresRepository.save` deletes the existing row for the
`property_id` before inserting — no more unique-constraint violation on
re-save; also what the re-score-on-override path needs.
- Solar already upserts, so it's unchanged.
The #1129 round-trip fidelity test stays green (delete-first is a no-op on
a first save). 2 new tests (re-save replaces, not duplicates). pyright
strict clean; AAA.
