fix(ios): use Xcode 26 workaround in sync-only mode

--sync was calling npx cap sync ios directly, so pod install failed
on Xcode 26 (objectVersion 70). Define run_cap_sync_with_workaround
once before sync-only and use it for both --sync and the full build;
remove the duplicate definition at Step 6.6.
