Fix language consistency in job search and match emails

1. Pass session.Language to MatchJobRequest in cv-search-job so the LLM
   uses the correct language-specific prompt for job titles and summaries.

2. Replace hardcoded "Manual job description" with a template-driven label
   (email.match.manual-job-label) seeded in English and Romanian, so the
   match email subject and Job row reflect the user's language.
