40 keys existed only in app_es.arb and fell back to Spanish everywhere else
(15 of them in English). Most were multi-device screens: hostGame, votar,
clueIs, whoDoYouThinkIsTheImpostor, waitingPlayersSeeWord.
Adds those plus the new keys for impostor awareness, the adjusted impostor
count, the eliminated-player notice and the reconnection screen.
51 keys across the 18 supported languages.
