Hello all,

This PR brings more improvements and additions to the app:

• Two more tabs to the Agents configuration tab: CIS-CAT and Commands.
• Adjusted space between title and value in some cards showing Manager or Agent configurations.
• Changed red and green colours to more saturated ones, following Kibana style.
• Even more CSS cleanup and reordering.
  • New typography.less file.
  • New layout.less file.
  • Removed cleaned.less file.
  • Reordering and cleaning of existing CSS files, including removal of unused classes, renaming, and more.
  • The Settings tab has been refactored to correct some visual errors with some card components.
