feat: fail screenshot/replay creation when a potentially sensitive widget is not masked

[vaind]

📜 Description

When a potentionally sensitive-content-containing widget is encountered and it is not masked (or unmasked explicitly), fail capturing replay in debug build by throwing an exception.

💡 Motivation and Context

This should help point users that they need to make adjustments to the privacy configuration. The code is only included in debug builds so it won't affect release builds in any way.

💚 How did you test it?

📝 Checklist

• I reviewed submitted code
• I added tests to verify changes
• No new PII added or SDK only sends newly added PII if sendDefaultPii is enabled
• I updated the docs if needed
• All tests passing
• No breaking changes
