Support Component placeholders in language API

Add support for passing Components as placeholders in LanguageManager (getComponent, getMessageList) and add Player extension overloads (sendMsg, trans) that accept component pairs. Replace usages of legacy serialized strings with direct Component placeholders across kits, scoreboard, and listeners (remove legacySerializer imports/usages). Also normalize placeholder keys (remove angle brackets in ConnectListener) and scope legacySerializer as private in Extensions.
