feat(12-01): wire matchDelta into pollDueSources; register TenderMatchingService

pollDueSources now collects genuinely-new tender IDs via an indexed
dedupKey pre-check (existing upsert doesn't report create-vs-update),
and calls TenderMatchingService.matchDelta(newTenderIds) once at the
end of the tick — the delta-only matching boundary (D-07). Changed/
re-seen rows are excluded, only genuinely new rows trigger matching.

TenderMatchingService registered as a provider in TendersModule and
injected into TenderIngestionService. Ingestion spec extended to
assert matchDelta receives only the new IDs, and is not called when
no new tenders were ingested this tick.
