- `EditEdgeModal`의 메인 컨테이너를 `div`에서 `form` 태그로 변경
- "저장" 버튼의 타입을 `submit`으로 변경하고 폼의 `onSubmit`에서 이벤트를 처리
- Enter 키를 통한 네이티브 폼 제출 지원으로 키보드 접근성 및 사용성 향상
- 모달 컨텐츠에 대한 테스트 코드(`EditEdgeModal.test.tsx`) 추가하여 100% 테스트 커버리지 달성

 ## 2024-06-26 - [Abbreviation Comprehension in ERD Nodes]
 **Learning:** Users without deep database administration backgrounds may not immediately recognize domain-specific abbreviations like "PK" or "FK" rendered as minimalist badges inside dense ERD nodes.
 **Action:** Always provide `title` attributes on technical acronym badges (like Primary Key / Foreign Key) to ensure clarity and improve accessibility without cluttering the space-constrained node UI.
+## 2023-07-04 - Native Form Submission for Modals
+**Learning:** React flow properties and components often lack default native form interactions. Converting modal contents strictly to `<form>` tags rather than `<div>` allows "Enter" key submissions, significantly increasing accessibility and UX.
+**Action:** Always wrap interactive input and button groups in a `<form>` component and ensure the submit action is bounded natively, especially for data entries and edits in overlays.
