Add agentic workflows page to website

Add a new /workflows/ page for browsing agentic workflow definitions
with search, trigger/tag filters, and sorting. Follows the same
patterns as the existing hooks page.

New files:
- website/src/pages/workflows.astro
- website/src/scripts/pages/workflows.ts

Updated files:
- BaseLayout.astro: add Workflows nav link
- index.astro: add Workflows card to homepage
- pages/index.ts: add workflows to counts
- utils.ts: add workflow type to icons, labels, and getResourceType
