Improve consistency for content not displayed in tables:

[1] Screens affected. This case applies for content view:

• Content view > Details tab > Sub-items default ordering
• Content view > Locations tab > Location content swap

[2] Styling: Header + content

• Header:

  background-color: $ez-color-base-pale;
  font-weight: 700;
  font-size: 1.0625rem;
  border-radius: .25rem .25rem 0 0;
  

• Content:

  background-color: $ez-white;
