fix(web): resolve TypeScript errors in test mocks and knowledge-base page

- Add missing Issue fields (parent_issue_id, acceptance_criteria, etc.) to test mocks
- Fix Agent mock fields to match actual type (runtime_config, owner_id, avatar_url)
- Import vi in test/helpers.tsx and add type annotation for mockAuthValue
- Add non-null assertions for array indexing in knowledge-base markdown renderer
