feat(html-report): add /html-report command for application tracker dashboard (#131)

Self-contained HTML dashboard generated from job_search_tracker.csv and the application archives: stat cards, status/sector/channel/funnel charts as hand-generated inline SVG (no CDN, fully offline), HTML-escaped interpolation throughout, and a filterable applications table. Includes Python guards for the command file and the reports/ gitignore rule.
