Add ranking, feast guards and i18n updates

Use Rank info in leaderboard display (adds playerrank, passes numeric score) and adjust message placeholders. Add prefix placeholder injection in LanguageManager. Introduce max-radius-teleport config and use it for player teleport on join. Restore broadcasting of player quit messages on disconnect. Enforce no-iron crafting before feast (deny craft, notify player & play sound) and cancel entity spawns until feast starts. Update config.yml with max-radius-teleport and refresh en_US language strings (add no_iron_before_feast and translate/update several GUI/perk entries).
