Track active bindPublishAccount calls in a per-platform map so a repeat
invocation reuses and focuses the existing window instead of spawning

open. Surface desktop_account_bind_limit_reached as a warning modal in
the renderer so users know to finish or close an existing authorization
before starting another.
