feat(cv-search-job): replace MyAiDbContext+ITemplateService with IEmailTemplateService

- Add ProjectReference to email-api-data; remove myai-data reference
- Program.cs: register EmailApiDbContext (no migrate), IEmailTemplateRepository
  (scoped), IEmailTemplateService (singleton); remove MyAiDbContext +
  ITemplateService registrations and their migration call
- CvSearchEmailSender: inject IEmailTemplateService; replace
  _config["Contact:ToEmail"] with GetOperatorCopy("email.search-results.subject")
  for operator copy logic; remove IConfiguration injection
- docker-compose: remove Contact__ToEmail from cv-search-job service block;
  add Database__* env vars to email-api service (needed for EmailApiDbContext)
