Renames the Go module path from openflux to
github.com/p1neappleXpress/OpenFlux and updates every internal import
(root module and mobile/), so the packages can be fetched and imported
by other Go projects.
Regenerated on main after #132, #122 and #125 (the same mechanical
rename, imports sorted by gofmt).
