feat: DB-backed localized templates + language-aware emails

- New Apis/myai-models project: MyAiDbContext (schema myAi), TemplateEntity,
  ITemplateService, DbTemplateService with 10-min in-memory cache
- Seeds EN+RO variants for all user-facing templates (match email, job search
  results email, HTML status pages, AI system prompt)
- Match result email now sent in user's UI language (en/ro)
- Job search results email now respects session language
- Language propagates: MatchJobRequest -> token -> session -> email
- Add Language column to JobSearchTokens and JobSearchSessions (default 'en')
- All three Dockerfiles updated to include myai-models in build context
