New users joining an existing workspace through an invite link were routed through the "Install your first apps" onboarding step, which is meant for workspace creation only. #22347 set `ONBOARDING_INSTALL_APPS_PENDING` inside `activateOnboardingForUser`, which is shared by both sign-up paths. Gate it per path like the connect-account step: `true` on `signUpOnNewWorkspace`, `false` on `signInUpOnExistingWorkspace`. Verified locally: invited users now go straight from create-profile into the workspace, and workspace creators still get the install-apps step. Covered by a unit test on the invite path and integration tests asserting the onboarding status per sign-up path (invite → `PROFILE_CREATION`; workspace creation → `SYNC_EMAIL` then `APPS_INSTALLATION`).
