Dynamic Portals

## Changelog 2.1.0 - Progress + Party Hub Update This is the main milestone of version 2.1.0. - Introduced a dedicated Progress + Party Hub GUI as the primary player experience. - Upgraded the mod from a mostly chat-command workflow to a focused in-game interface. - Added a two-tab structure (Progress and Party) to keep core actions simple and fast. - Added portal cards, requirement details, pagination, and clearer progression visibility. - Added integrated party actions in the same screen: create, join, leave, and dissolve. - Improved usability with responsive UI behavior across GUI scale and window size changes. - Press "H" Button in game (Default). Commands are still supported, but the new Hub is now the central way to interact with the mod.
