Add Game Over UI and logic integration

Introduces a Game Over panel to the HUD, with supporting styles and controller logic. The MainStation destruction now triggers a game over state, displays the overlay, and disconnects the player from the network. Includes new GameOverHUDController, updates to GameHUDController, and related UI/UX improvements.
