R-516: the formal forms in Go literals move into the bundle in the te-form

22 Go-literal messages (escrow handler, share password page, export
upload, network-storage uid/remove/attach failures) are bundle keys with
te-form Hungarian and English; a detached attach failure renders in the
reader's language. The NAS refusal says „Válassz". Setup wizard,
recovery-info.txt (R-554) and the SMART/fill-watch wire texts are left.
