chat-view: Split new SMS conversation message in two lines
The message for new SMS conversations is too long for some screens and prevents both the end of the message and the "Send" button to be visible on the screen. Split the message into two lines to improve readability and allow sending the message without requiring to rotate the phone.
I don't have much experience with GTK apps, so there might be some other more elegant solution to fix this issue. I would be happy to improve this solution if given some pointers on how to do it.
Below are some pictures from my pinephone. Sorry for the low picture quality, I struggled taking the pictures, but I believe they're clear enough to see the issue.
