Add internet job search feature (cv-search-job)

- New cv-search-models shared library: EF entities + CvSearchDbContext for cvSearch schema (JobSearchTokens, JobSearchSessions, JobSearchResults tables)
- New cv-search-job worker service: polls DB for pending sessions, scrapes job boards via configurable HTML scraping, runs LLM scoring via cv-matcher-api, emails ranked results
- cv-matcher-api: JobTokenService creates one-time tokens; JobSearchController handles link clicks and creates sessions
- api: proxies job-search start endpoint, appends job search link to match result email
- CI workflow updated to build and push myai-cv-search-job:staging image
- CLAUDE.md documentation added for all affected services
