feat(supplier): Plan 4 Task 7 — SupplierCsvParser (streaming) + SupplierPortalClient::downloadLeadsCsv
SupplierCsvParser — pure streaming-generator CSV parser:
- BOM (UTF-8 EF BB BF) + CRLF normalization
- Malformed rows (< 6 columns) skipped + Log::warning
- 5 unit tests: empty / 1 row / 1000 rows / malformed / BOM+CRLF
SupplierPortalClient::downloadLeadsCsv(CarbonInterface, CarbonInterface):
- GET /admin/report/index?type=49 через существующий request() helper
- Наследует auth/retry семантику (401 → RefreshSession, 5xx → Transient, 4xx → Client)
- 3 unit tests через Http::fake: 200 / 401 retry / 500
