style: unify Loop Monitor UI design with improved clarity

Major visual improvements across all components:

Left Sidebar (Loop Cards):
- Enhanced card styling with better shadows and borders (4px left border)
- Improved hover states with subtle elevation
- Better selected state with primary color highlight
- Increased padding and spacing (1rem padding, 0.75rem margin)
- Cleaner status indicator badges

Right Panel (Detail View):
- Added background containers to all detail sections with borders
- Improved section headers with bottom borders for clear separation
- Enhanced progress items with individual card styling
- Better visual hierarchy with consistent spacing (1rem gaps)
- Added info-box component for V2 loop information

Meta Information:
- Detail-meta items now have pill-style backgrounds
- Dashed separator line for better visual grouping
- Improved spacing and padding

CLI Steps:
- Enhanced step cards with better borders and hover states
- 3px left accent border for status indication
- Smooth transitions on hover

Typography & Colors:
- Unified border-radius: 0.625rem for sections, 0.5rem for items
- Consistent background: hsl(var(--muted) / 0.25) for sections
- Better border opacity: hsl(var(--border) / 0.5) and 0.6 variants
- Improved font weights and sizes for clarity

Overall result: Cleaner, more professional interface with better visual hierarchy and clarity.
