* fix: PrintHeader kills headless startup when no console is attached

Console.WindowWidth/WindowHeight throw IOException when the process has no
console at all (Windows service, container, detached process manager), so the
banner took the server down before it did any work. Read the width once through
a guarded helper and fall back to the same narrow layout already used when the
window height is unknown.
