feat(desktop): surface baijiahao challenge-required failures with actionable copy

Baijiahao throws baijiahao_challenge_required when its risk control flags
the network environment, but PublishManagementView previously showed the
raw "code: ..., message: ..." string. Route the error through the existing
normalizer pipeline so users see a clear "需要人机验证 + 去后台手动完成
一次发稿" prompt instead.
