fix(tui): treat global events as default location for integration refresh

The v2 integration refresh converted event metadata directly into a
Location.Ref, so the global routing sentinel (directory "global") was
sent to the server as a real filesystem location. LocationServiceMap
built the full project graph for it, and Fff.create({ basePath: "global" })
failed on every refresh after OAuth callback disposal. Map global events
back to the current default location instead.
