Release version 1.2.4 - Fix admin table borders and checkbox layout

Fixed:
- Admin table borders still visible despite v1.2.3 fix - added !important flags
- Help icon positioning at right edge instead of next to label - changed to flexbox layout
- Increased checkbox margin from 8px to 12px for better spacing

Technical:
- Added border-collapse: collapse !important to force borderless tables
- Changed label layout from float to inline-flex for proper help-tip positioning
- Added comprehensive border removal with !important on all table elements
