Remove legacy modules, add language & scoreboard

Large refactor removing many legacy subsystems (abilities, kit system, database repos, recraft, world manager, extensive config classes, lunar/luckperms integrations and various listeners/commands). Introduces a lightweight LanguageManager, AntiRunningManager, ScoreboardManager, ConnectListener and a SoupListener; simplifies the main SpeedHG plugin to initialize these components and register the connection listener. Build changes: update Gradle wrapper to 8.10, remove paperweight and several external dependencies, add fr.mrmicky:fastboard and simplify shadowJar/build task configuration. Adds default language resource (languages/en_US.yml) and updates plugin/config resources. Purpose: simplify and decouple the plugin, reduce dependency surface and prepare for a leaner, modular rewrite.
