R-516 items 1+4: the menu says Hibakeresés; the storage pages use the te-form

Item 1: the always-visible 'Debug' menu item reads 'Hibakeresés' in
Hungarian (key layout.hibakereses; English stays 'Debug'). Item 4: four
formal forms on the storage pages (Adjon hozzá, Csatlakoztasson,
Válassza ki x2, Önnek) are now te-form. The parity fixtures change by
exactly these bytes (a deliberate copy change, not a regeneration);
HU_FORMAL_CEILING 17 -> 14. Item 2 was already fixed (slice 1).
