Promote develop to main: Phase 3 AI submenu Playwright tests

[workcontrolgit]

Summary

• Phase 3: Add AI submenu page objects and test suites for all 4 AI pages
• Updated screenshot spec to replace stale ai-chat tests with new AI page tests
• Graceful degradation: all tests skip when AI is disabled (aiEnabled=false)

Changes

• New page objects: ai-assistant.page.ts, ai-hr-insight.page.ts, ai-nl-search.page.ts, ai-vector-search.page.ts
• New test suites: tests/ai/ai-navigation.spec.ts, ai-assistant.spec.ts, ai-hr-insight.spec.ts, ai-nl-search.spec.ts, ai-vector-search.spec.ts
• Updated tests/screenshots/blog-screenshots.spec.ts to target new AI routes

Test plan

• Run npx playwright test tests/ai/ to verify navigation and page tests
• Run npx playwright test tests/screenshots/ to verify screenshot tests
