Fix template priority field name and improve admin form styling

Template fixes:
- Fixed column name mismatch: use 'default_priority' instead of 'priority'
- Updated manage_templates.php API INSERT and UPDATE queries
- Updated TemplatesView.php to use correct field name in PHP and JS

CSS improvements for .setting-row:
- Better flexbox layout with flex-wrap for responsiveness
- Proper styling for inputs, selects, and textareas in setting rows
- Labels now align to top (better for textareas)
- Added focus states with amber glow effect
- Improved checkbox styling within setting rows
- Better mobile responsive behavior (stacked layout)
- Updated cache version to 20260126a
