Blocks toolbar design renovation

[Svaney-ssman]

The design team has redesigned the UI details of the toolbar, including its size, spacing, shadows, radius, and button sizes. The toolbars mentioned below need to be uniformly modified.
Please focus solely on the UI redesign for this issue. We don't need to address any functional discrepancies at this stage. Let's ensure the user interface aligns with the updated design specifications. If you encounter any functional issues while implementing the UI changes, you can note them, but there's no need to resolve them in this phase.
