fix: conditionally apply web-only cursor style to avoid TypeScript error

[kirstilynn]

🧠 Context

This component previously used:

// @ts-ignore supported on web
cursor: 'grab',

to support cursor styling on the web platform. However, this still triggers a TypeScript error when using "jsx": "react-native" or when TypeScript re-validates style against ViewStyle — because the inferred object type includes cursor, which isn't allowed on native.

Even with "skipLibCheck": true, the error shows up at usage, not declaration, so @ts-ignore isn't enough.

---

✅ What’s fixed

The style is now wrapped in a platform check:

container: {
  ...(Platform.OS === 'web'
    ? { padding: 10, cursor: 'grab' }
    : { padding: 10 }),
},

This ensures the cursor property only exists at runtime when Platform.OS === 'web', so it's no longer included in the type — and TS no longer complains when passing it to a <View style={...}>.

---

📌 Why this matters

• Removes the need for @ts-ignore
• Fixes valid TS errors that still happen despite the ignore
• Maintains behavior for web with zero runtime impact elsewhere

---

Let me know if you'd like to validate this further or want additional changes.
