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.
