refactor: Rename component pages to program pages and remove tools concept

The 'tools' concept was just a filtered view of programs and added unnecessary
complexity to the frontend. This commit:

- Removes ToolCard.tsx and Tools.tsx (pages/components never used in router)
- Renames ComponentDetail.tsx → ProgramDetail.tsx (exports ProgramDetailPage)
- Renames ComponentRedirect.tsx → ProgramRedirect.tsx (exports ProgramRedirect)
- Updates imports in routes.tsx to match new file names
- Fixes stale comment in hooks.ts

Frontend naming now aligns with the unified programs model.
