fix: use turbo build in playwright webServer and add build step to CI e2e job

The e2e CI job was failing because the webServer command ran
`pnpm --filter @object-ui/console build` which runs tsc directly.
tsc failed (exit code 2) because workspace packages' dist/ directories
didn't exist (the build job runs on a separate VM and artifacts aren't shared).

Changes:
- playwright.config.ts: Use `turbo run build` which properly builds
  dependencies before the console (respects ^build dependency chain)
- ci.yml: Add explicit build step before Playwright tests, so the
  webServer's turbo build is a cache hit (~320ms)
