OmniPanel v18.5.300

Rules GUI
- Existing installations now receive default config-only rules when rules-gui.entries is missing.
- Every rule entry opens a readable detail view.
- Added Read in Chat, Back, Close, page navigation, and working Rules Information actions.
- Rules remain editable only through config.yml.

Kit Manager and /kit
- Added /kit manager, /kit manage, /kit admin, /kit control, and /kit setup routes to the existing Kit Manager.
- Added the manager suggestion to /kit tab completion for authorized staff.
- Connected Paper AsyncChatEvent input to the existing KitSystem chat editor so search, create, display-name, cooldown, rank, permission, duplication, icon, and one-player cooldown-reset prompts work on Paper 1.21.11.
- Kit information cards now print their information in chat instead of acting like dead buttons.

Architecture
- Reused the current RuntimeCommandSupport chat/command/inventory route and the current KitSystem backend.
- No new listener, patch manager, duplicate kit backend, or old-source revert was added.
