Add spacing to the bottom of the UI

[Nico-Kestra]

Describe the issue

In general, on the UI, the pagination or the elements at the bottom are too close to the edge. I would tend to add some space to avoid this.
For example, on blueprints, plugins, or even executions:

Add 64px please.

Environment

• Kestra Version:
• Operating System (OS/Docker/Kubernetes):
• Java Version (if you don't run kestra in Docker):
