Adds an "Install your first apps" step to the V2 onboarding, shown right
after import-contacts. It lets users opt into installing marketplace
apps (Call recorder and People Data Labs for now) during onboarding.

- New backend `OnboardingStatus.APPS_INSTALLATION` (between SYNC_EMAIL
and PROFILE_CREATION); V1 auto-skips it.
- The primary button sends the selected app ids to the server via
`triggerInstallAppsOnboardingStep`, which enqueues a dedicated job that
installs them asynchronously so onboarding isn't blocked. Skip continues
without installing.
- The workspace is credited per app on successful installation. Credits
are env-driven via `ONBOARDING_INSTALL_APPS_CREDITS_REWARD_PER_APP`,
shown as "Earn +N free credits (1 per tool)".
