🎨 Palette: Standardize admin tactile feedback and focus states

[bbaaxx]

💡 What: Added active:scale-95 tactile feedback and standardized focus-visible:ring-2 focus states across the administrative interface.

🎯 Why: Improves the "feel" and responsiveness of the admin dashboard while ensuring better keyboard accessibility and a consistent user experience with the rest of the application.

📸 Before/After: Interactive elements like "Add New Move", "Add Category", "Save", "Edit", and "Delete" now provide visual scaling feedback on click/tap and have clear, consistent focus rings when navigated via keyboard.

♿ Accessibility: Switched to focus-visible where appropriate to ensure focus rings only appear for keyboard users, avoiding persistent rings after mouse clicks while maintaining WCAG compliance for keyboard navigation.
