Adds CosinexAdapter to TendersModule's providers and registers it with
SourceRegistry at DI boot, alongside DoeOpenDataAdapter/NetServerAdapter
(cosinex-dtvp is not AGB-denylisted, so registration succeeds). Seeds a
cosinex-dtvp TenderSourcePollConfig row with isActive: false, matching
the ai-netserver "framework ready, activation deferred" stance (D-02).
tsc --noEmit clean; src/tenders slice: 21 files, 221/221 tests pass
(205 pre-existing + 16 new cosinex.adapter.spec.ts).
