feedback5 WI: server toasts and ticker lines carry msgid + params so the client shows them in the player's language

messaging.js: a toast / CUSTOM ticker line is a string (its own msgid) or a shared/i18n.js msg(); frames keep
the Chinese `text` (older clients) and add `msgid` / `params`; config.broadcasts lines carry their `args`
(the client fills the localized broadcast template; the player name {0} is never translated). Templated call
sites send msg(): the grant toast 「X：获得Y」, the summon-range and terrain withdrawals, the 联防 line,
eliminated / left lines, the 远见 / 奇迹 stack payouts and the 维多利亚 hammers; game-data names go as dn().
The protocol stays backward compatible (new fields optional). Tests that captured m.toast's argument render
it with renderMessage. No gameplay change: golden unchanged.
