feat: HQ redesign

Both from the final review, and the first one overturns a call I got wrong.

The aria-hidden sweep that makes aria-modal true also swallowed the toasts.
ToastProvider renders inside the app root, and every modal-raised confirmation
is toasted *before* its dialog closes — "Saved …", "Deleted …", "Removed …" —
so each one was inserted into a hidden subtree and never announced. Un-hiding
a live region afterwards does not replay what it missed. The toast layer is
portalled to the body carrying the dialog-layer attribute, which exempts it
from the sweep, and sits above the dialog: a toast explaining why a dialog's
action failed is no use behind it.

EmptyState's action was narrower than the call site it replaced. The old
first-workflow button carried loading={isPending}; the new one carried
nothing, so a double click created two workflows. The action is a union now —
a link takes no pending state, a handler takes loading and disabled.
