Phase 9 Wave 1: add ReleaseMedium discriminator + Session/Mix metadata

Add ReleaseMedium enum (Cut/Session/Mix) and two 1:1 satellite entities (SessionMetadata, MixMetadata) with EF configs and an additive migration. ReleaseDto.ReleaseType is now nullable, nulled for non-Cut at the converter. Existing releases default to Cut via column default; no data migration.
