saveResource() called app.modal.close() then, after an intervening
await loadResources(), conditionally app.modal.open() to show a newly
created OAuth client's secret. app.modal is a singleton -- close()
immediately followed by open() in the same tick collides with Bootstrap's
hide-transition guard (show() silently no-ops while _isTransitioning is
still true from the just-started hide()). The await made this race
unlikely to lose in practice, but not guaranteed to -- found while fixing
the same bug (with no such await, so guaranteed to lose) in jump-host and
proxy's API-token create flows.
Now the resource-edit modal is only closed when we're NOT about to
immediately show the OAuth secret; app.modal.open() alone already
overwrites the (already-visible) modal's content in place, no close()
needed first.
