R-516: the formal forms the gate did not count are in the te-form; the gate's stems widened

49 Hungarian values on the debug (RESET prompt), storage, network-storage, security, system,
deploy, restore and remote-backup copy moved from the formal („ön") to the product's te-form
(„írd be", „add meg", „hozz létre", „biztosan eltávolítod", „engedélyezd", „próbáld", ...).
i18n_missing_gate.py's stem list widened by 33 stems (+ one listed third-person exception,
„sora adja meg"); it counted 61 on the previous bundle and counts 0 now, ceiling stays 0.
Decoys: a widened-stem form convicts, its te-form twin and the third-person phrase pass.
38 parity fixtures changed by exactly those bytes. Seven Go-side keys listed as REWORDED in the
go-parity map. Pinned by TestR516_WidenedFormalFormsAreGone; two tests that quoted the old
words follow them.
