Add ranking system and /ranking command

Introduce a ranking system: add Rank enum and RankingManager enhancements (isRankingEnabled toggle, getRank(), RR change handling, rank-up/down detection and player notifications with titles/sounds). Add a new /ranking admin command (toggle, status, rank) with tab completion and register it in plugin startup. Surface player rank on the scoreboard (ScoreboardManager) and add related language entries and plugin.yml permission/command metadata. Logging updated to include ranked state.
