Multiple critical fixes for dashboard v2:
**1. ResizeHandler error - updateContainerWidth is not a function**
- resizeHandler.js:288 was calling non-existent method
- Removed call - containerWidth tracked by ResizeObserver
- Resizing now functional
**2. DragDrop bug - widgets can't be released**
- endDrag() destructured widgets, originalX, originalY from dragState
- These fields were never added in startDrag()
- Added widgets parameter to initWidget() and startDrag()
- Store originalX, originalY, widgets in dragState
- dashboardManager now passes current tab widgets
- Widgets can now be dropped properly
**3. Widget content overflow**
- Added base .rpg-widget CSS: overflow: hidden, box-sizing: border-box
- Prevents content extending beyond widget bounds
- max-width: 100% on children
**4. Automatic layout migration**
- Old 12-column layouts (w: 8, w: 12) cause 500%+ widths in 2-4 column grid
- Added migrateOldLayouts() method
- Detects widgets with w > current column count
- Runs auto-layout to reposition for responsive grid
- Clears and re-renders current tab with new positions
- Saves migrated layout automatically
**5. Tab rendering**
- Implemented renderTabs() method
- Displays tab buttons with icons and names
- Active state highlighting
- Click handlers to switch tabs
**6. Collision prevention**
- Modified dragDrop endDrag() to check collisions
- Same-size widgets: swap positions
- Different sizes: revert to original
- Prevents overlapping widgets
**7. Edit mode fixes**
- Fixed edit button to call toggleEditMode()
- Added CSS to hide resize handles when not in edit mode
- Handles only visible in edit mode
**8. Icon-only header buttons**
- Auto-Arrange and Edit buttons now icon-only
- Saves horizontal space in header
