Clarify how to save layout changes

hey @quicksketch tried a different approach to handle this, instead of changing the warning message i tried to improve the UI for toolbar with more focus on buttons so it doesn't feel like a footer. this will also tackle the situation where if the layout has more elements the message stays on top of page and the user just scrolls past it this new button design will be visible clearly to user in such case.
attaching a patch for this, if this solutions looks good will create a MR.

Awesome, I think that alone will be a big help.

Nice! I tweaked it a tiny bit so that it matches 🐛 Use Hand/Move cursor for block library Fixed .
