Add configurable GUI system and route menus through service

- introduce `ConfigurableGuiService`, `GuiConfigManager`, and `GuiContext`
- move GUI behavior to config-backed definitions in `guis.yml`
- update existing GUI entry points and `/enderchest` view to delegate to the new service
- initialize the new GUI service during plugin startup and remove legacy GUI listeners
