Add searched location to job search results email

Show the candidate's location in the scan summary block of the results email
alongside keywords and providers, for both en and ro templates.

- CvSearchEmailSender.SendResultsAsync accepts location and passes it to BuildScanSummary
- BuildScanSummary passes {{location}} to the template (falls back to '-' when absent)
- CvSearchJobTask passes session.Location to SendResultsAsync
- New migration AddLocationToScanSummaryTemplate updates both language variants of
  email.search-results.scan-summary to include a 'Location / Locație căutată' row
