feat: replace direct MailKit in cv-search-job with IEmailApiClient Refit call

- CvSearchEmailSender now injects IEmailApiClient instead of IConfiguration+MailKit
- BuildBody updated to produce styled HTML job cards
- CvSearchJobTask passes only filename (not full path) to email sender
- IEmailApiClient registered in Program.cs with EmailApi:BaseUrl + InternalApiKey
- MailKit removed from cv-search-job.csproj
