fix: LEAP-828: Add handling for carriage return in domManager

[Gondragos]

1. Update the dom Managed to incorporate the handling of carriage return (CR) characters. This is a necessary change as some operating systems or browsers use both line feed (LF) and carriage return characters.

2. Previously we had a problem with missing regions when we are trying to render annotation from results that have a wrong order. It was caused by the problem with detecting area type (it thought it was an classification) when we have excessive fields in result (like a text). So in this commit I tried to fix it by adding expected values from value after creating an area and directly to the text field of RichTextRegion. (see HumanSignal/label-studio-frontend@6ef0657#diff-9386d502ec5e5d9e8b50c2c679499430ca58728900aac1a43de33d13ee2648f4)
