Close create wizard modal as soon as ddev config succeeds

handleSubmit awaited the entire post-create chain (start, then for
WordPress: download core + install) before ever calling onClose(),
so the modal overlay sat there for the whole multi-step process with
no way to see what was actually happening — the terminal panel that
already tracks this operation's live output was hidden behind it.
Close right after the quick config step succeeds and let post-create
continue as a tracked background operation; failures still surface
via the existing toast/terminal-panel error handling regardless of
modal state.

Also extracts the project-name validation helpers out of
CreateProjectModal.tsx into their own module — mixing component and
non-component exports in one file breaks React Fast Refresh.
