Removes height constraint from the disclaimer button

[dusi]

📲 What

Removes height constraint form the disclaimer button in order for the label to not have a limited height.

🤔 Why

Limiting the height makes the label cut off some of the text which is not desirable. This happens on smaller devices like iPhone SE or when users set larger font size.

🛠 How

• By removing the height constraint on Disclaimer Text View (labels define their intrinsic size based on their text)
• By also setting placeholder width & height (this is necessary to make Interface Builder happy during the design time - the reason for this is that without any text at design time Xcode can't calculate the final height of the top most Scroll View)

Because the label is sized based on its text it does not need whole 60 pts in its default state (which is why there are new screenshots). You can inspect the diff and see that the card is now couple points shorter in height (that's why it was necessary to re-record)

It looked good in all test cases 🚢
