Base class architecture improvements:
- Centralize all panel layout, styling, and behavior in ControlBase
- Implement consistent generateContent() pattern for subclasses
- Add proper flexbox layout with fixed header and scrollable content
- Standardize title styling, positioning, and scroll behavior
Panel layout fixes:
- Fix content positioning to appear inside panels instead of floating above
- Implement proper height management (expands with content up to browser height)
- Add correct scroll boundaries with only content area scrolling
- Position resize handle outside scroll area to avoid scrollbar interference
Visual improvements:
- Fix rounded border appearance with proper overflow handling
- Ensure header respects panel corner radius
- Add proper content margins and padding
- Improve resize handle positioning and visibility
Architecture standardization:
- All panels now follow same base class pattern
- Individual panels only provide configuration and content generation
- Eliminate duplicate styling and layout code across controls
- Consistent behavior across all panel types

Panel UI improvements:
- Replace heading elements (h1-h6) with styled divs to avoid navigation interference
- Change ContentsControl position from northwest to west for better accessibility
Panel collapse/expand enhancements:
- Fix panel dragging to prevent unexpected positioning jumps
- Keep panel width and upper-left position when collapsing to header-only mode
- Complete height reduction when collapsed (no minimal size maintained)
- Toggle resize handle visibility based on panel state
Resize handle improvements:
- Change resize symbol from arrow to clean dot (●) in bottom-right corner
- Remove background circle, show transparent dot only
- Fix resize direction to properly follow mouse movement from bottom-right
- Set dynamic minimum size constraints (header height + padding)
- Allow arbitrary panel sizing with proper bounds checking
- Reset panel size to defaults when closed/collapsed
