feat(ui): migrate cliproxy page to design system Config archetype

Wrap master-detail layout in PageShell + PageHeader + ConfigLayout.
PageHeader carries the brand strip (Zap icon + CLIProxy title +
account-management description) and refresh button. The existing
sidebar (Quick Setup CTA, sectioned providers list, variants list,
ProxyStatusWidget, footer connection summary) becomes ConfigLayout's
left rail; ProviderEditor and EmptyProviderState become the form pane.

Pure layout migration: every sub-flow still mounts correctly --
QuickSetupWizard dialog, AddAccountDialog (URL action=auth deep-link),
AccountSafetyWarningCard for gemini/agy, provider selection persisted
to localStorage and URL deep-link, all bulk pause/resume/solo/delete
mutations untouched. ProviderEditor (which contains the form + raw JSON
internally) remains as a single 'form' slot.
