✨ style(JSONEditor): add AGPL-3.0 license header, clean imports & refine Banner UI

* Added full GNU Affero General Public License v3 header at the top of `JSONEditor.js`.
* Removed unused `IconCode` and `IconRefresh` imports to eliminate dead code.
* Set `closeIcon={null}` and applied `!rounded-md` class for `Banner`, improving visual consistency and preventing unintended dismissal.
* Normalized whitespace and line-breaks for better readability and lint compliance.
