🎨 Palette: [UX improvement] Update AI terminology in prompt-studio and ProjectsLayout

[seonghobae]

💡 What
Updated AI terminology labels in prompt-studio and ProjectsLayout to match the Naruon UI/UX terminology mapping guidelines. Specifically, updated occurrences of '요약' (Summary) and '인사이트' (Insight) to '핵심 맥락' (Core Context) and '판단 포인트' (Decision Point) respectively.

🎯 Why
To adhere to the UX guidelines which dictate that Naruon is an evidence-based AI Email Workspace that doesn't just summarize but connects context and aids judgment.

📸 Before/After
Before:

• '업무 요약', '문서 요약/초안 작성', '의사결정 요약'
• '데이터 분석 인사이트'
• '실행 준비 요약', '요약 대기'

After:

• '업무 핵심 맥락', '문서 핵심 맥락/초안 작성', '의사결정 핵심 맥락'
• '데이터 분석 판단 포인트'
• '실행 준비 핵심 맥락', '핵심 맥락 대기'

♿ Accessibility
N/A (No structural changes to interactive elements; only display text was updated).
