🎨 Palette: Improve keyboard accessibility for form inputs

[seonghobae]

💡 What: Wrapped input and button groups for creating projects and connections inside <form> elements instead of plain <div> containers, and changed action buttons to type="submit". Removed redundant onClick handlers where handled by the form submission.
🎯 Why: To enable native keyboard interactions (pressing Enter) inside inputs, ensuring a seamless user experience when creating resources without requiring the user to manually click or tab to the submit button.
♿ Accessibility: Added native keyboard submission support for primary resource creation inputs, significantly reducing interaction friction.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 51 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

#696에서 동일한 프로젝트·연결 생성 폼 전환을 포함해 인라인 프로젝트 생성, 다이어그램 검색, 캔버스 검색까지 더 넓게 처리했고 Enter 제출·중복 실행 방지 회귀 테스트도 추가했습니다. 이 PR은 #696의 부분집합이며 별도 테스트가 없고 동일 App.tsx 구간에 충돌을 만들므로 중복 PR로 종료합니다.

#696에서 동일한 프로젝트·연결 생성 폼 전환을 포함해 인라인 프로젝트 생성, 다이어그램 검색, 캔버스 검색까지 더 넓게 처리했고 Enter 제출·중복 실행 방지 회귀 테스트도 추가했습니다. 이 PR은 #696의 부분집합이며 별도 테스트가 없고 동일 App.tsx 구간에 충돌을 만들므로 중복 PR로 종료합니다.

알겠습니다. 이 PR의 작업은 더 광범위하게 적용된 #696 PR과 중복되므로 현재 작업을 중단하고 이 PR은 종료된 것으로 간주하겠습니다.
