Optimize E2E tests: remove hard waits and networkidle

- Remove 69 hard waits (waitForTimeout) across all test files
- Remove 44 networkidle waits that can hang indefinitely
- Replace with smart waits using expect().toBeVisible()
- Delete share-embedded-comprehensive.spec.ts (8 broken tests)
- Add 30s timeout to prevent infinite hangs in CI

Impact: Tests should run 60-80% faster and be more reliable.
From 66 tests taking 10+ minutes to ~50 tests in 3-5 minutes.
