feat: stack note complete content

[Schwehn42]

Description

Closes #2627
Reworks the stack view so that more content ist shown. If exceeding the height limit, the notes are scrollable. On Desktop, the parent will be displayed on the left hand side, while the child notes are on the right hand side. On Mobile, notes will remain on top of each other.

• reorder notes on desktop
• make note content height dynamic
• add media query for mobile
• add a styled scrollbar
