Add Tools, Recipes, and Glossary pages to web app

Three new pages matching the existing incident-card design:

- Tools (71 tools, 13 categories): searchable/filterable catalog of
  open-source GenAI security tools with category pills, risk badges,
  and external links. Data from shared/TOOLS.md.

- Recipes (21 recipes, 5 architectures): security implementation
  patterns for RAG, MCP, OT, Agentic AI, and Data Pipelines. Cards
  link to full recipe content on GitHub. Data from shared/RECIPES.md.

- Glossary (37 terms): searchable A-Z terminology with definitions
  and OWASP entry cross-references. Data from shared/GLOSSARY.md.

All three pages reuse existing CSS classes (incident-card, filter-bar,
pill-group, card-grid) for visual consistency.
