Move 24 defcomp definitions from Python string constants in components.py to 7 grouped .sexp files under shared/sexp/templates/. Add load_sexp_dir() to jinja_bridge.py for file-based loading. Migrate events and market link-card fragment handlers from render_template to sexp. Delete 9 superseded Jinja HTML fragment templates. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
