Rename EmailApiDbContext to EmailDbContext and EmailTemplates table to Templates

Refactoring:
- Rename EmailApiDbContext class to EmailDbContext for consistency with other DbContext naming
- Rename DbSet property from EmailTemplates to Templates
- Rename table from EmailTemplates to Templates
- Update all references in Program.cs files (email-api, api, cv-search-job)
- Update all migration files and model snapshot
- Fix cv-search-job migrations assembly name: email-api-data → email-data

This improves naming consistency across the solution.
