🎨 Palette: [UX improvement] Add accessible context to edge edit buttons

[seonghobae]

💡 What: Added specific source/target table contexts to the aria-label attributes of generic "Delete", "Cancel", and "Save" buttons within the Edit Edge Modal.
🎯 Why: Generic buttons like "Cancel" or "Save" provide poor context to screen reader users when isolated. By specifying the edge relation (e.g. a에서 b 관계 삭제), it becomes completely unambiguous.
📸 Before/After: Visuals are unchanged; screen reader auditory experience is explicitly clear.
♿ Accessibility: Ensures generic action button labels are robustly contextualized according to WCAG principles.
