SuperLobby Parkour

Bug Fixes & Adjustments: * Fixed an issue where events disabled in the setup GUI would still trigger during the parkour roulette. The generator now correctly reads the active events from the configuration. * Fixed a configuration path bug that caused saved Start Zones to disappear when re-opening the setup GUI to edit an existing arena. * Fixed the Modrinth update checker failing to connect. The HTTP request now includes the strictly required User-Agent header for the Modrinth API. * Fixed formatting issues in GUI titles, items, and the leaderboard. The language manager was updated to allow disabling the chat prefix in contexts where it was causing visual clutter.
