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.

 **MinAgent: 0.131.0** (unchanged — no new agent route is read).
 
 - **R-542:** `GET /api/disks/candidates` no longer offers a drive that backs a REGISTERED storage path — not under `initialize` (the format wizard renders that list as-is, so a household's in-use data drive was offered for formatting) and not again under `attach`. The join is the guest's own mount table (a registered path's mount source is the host device). Fail-safe: an unreadable mount table empties `initialize`; `attach` passes through. Tests `TestR542_*` (two red-proofs observed).
+- **R-516 (the Go-literal leftover):** 22 messages that lived as Go string literals — the escrow handler (6: no password set, too many attempts, staging failed, a code already being made, a code not shown, no active job), the share-page password (2), the export upload size mismatch, the network-storage uid refusal and in-use removal, and the network-storage attach failures (10 categories + the Windows-name tip) — are bundle keys now (`api.escrow.*`, `api.share.*`, `api.export.*`, `api.netstorage.*`), in the te-form in Hungarian (14 of them were in the formal „ön" form: „próbálja", „állítson be", „várja meg", „indítsa", „töltse", „ellenőrizze", „használja", „kapcsolja be", „állítsa", „jelezze", „távolítsa el", „adjon meg"), with English. A failed attach job is rendered in the READER's language at the status read (it ran detached; it keeps its category, server and uid). The NAS app-namespace refusal says „Válassz" (stays a settings constant). Left on purpose: the setup wizard and `recovery-info.txt` (R-554), and the SMART and fill-watch texts — they are the hub event's message, mailed as is (wire text). Tests `TestR516_GoLiteralFormalFormsAreGone` (keys in both languages + a source scan with a positive control), `TestR516_NetAddFailureFollowsTheReader`; red-proofs `felhom.eu/documentation/audits/night-burndown-2026-10-06/ctrl/R-516-red*.txt`.
 
 ## v0.301.0 — one short stop per backup tier; restores replay before the app starts; the family window reopens a command-closed sign-up (R-518, R-638, R-717; `09` §3 154, 156) (2026-10-06)
