Consolidate all migrations into single InitialSchema migrations

Deleted all incremental migrations and regenerated fresh InitialSchema migrations
that contain the complete, correct schema from the start:

- CvMatcher: InitialSchema with 3-column unique constraint on Results
  (CvDocumentId, JobDocumentId, Language)
- Email: InitialSchema with Templates table (consolidated from EmailTemplates)

This creates a cleaner migration history and faster fresh deployments. Since there
is no production data, consolidation is safe and improves maintainability.
