 * Account details drawer form.

 * Client-side validation runs through TanStack Form's `onDynamic` +
 * Zod — same rules the server uses, re-declared here so field errors
 * show up without a network round-trip. On submit the form diffs
 * against the original row and sends only the *changed* fields as a
 * patch, plus the `vid` the form was opened with, so a concurrent edit
 * elsewhere comes back as `admin.users.versionConflict` and we surface
 * a reload prompt.
