refactor: Simplify card shortcuts and enhance card control in editor

- Removed individual card shortcuts for dungeon and graphics categories to prevent hash table overflow, consolidating functionality into a Card Browser.
- Introduced a context-sensitive card control feature that dynamically displays relevant cards based on the active editor.
- Updated PaletteEditor to clarify its use of internal tabs instead of separate cards.
- Registered multiple cards in MessageEditor and OverworldEditor, improving visibility and management of editor functionalities.
