v4: every request about a user, and the dump editor's path, come from one builder each — fourteen places wrote /api/users/<key>/… by hand, some encoding a handle (@alice%40music.example) and some not, a slug never; userApiUrl (src/utils/shared/urls.ts) now writes them all, by the user's id or by @ and the handle a page's path gives, each segment encoded. The editor's path was the dump's page's with /edit added in two places; dumpPath takes the view, as userPath and feedPath do.
