Implement responsive scaling for info widgets and fix sizing issues:
**1. Container-Responsive Info Widgets (style.css)**
**Calendar Widget:**
- Add flexbox layout (height: 100%, flex-direction: column)
- Change font sizes from vw to rem for better scaling
- Calendar day now uses clamp(1.5rem, 2.5rem, 3.5rem) to fill space
- Add flex-shrink: 0 to top/year, flex: 1 to day
**Weather Widget:**
- Add container wrapper (height: 100%, justify-content: space-around)
- Weather icon scales with container: clamp(2rem, 8vh, 4rem)
- Forecast text uses rem instead of vw
- Both elements marked flex-shrink: 0
**Temperature Widget:**
- Container fills height with flexbox centering
- Thermometer scales: clamp(4rem, 60%, 8rem) height
- Tube/bulb use percentages (40% width, 70% height)
- Text value uses rem units
**Clock Widget:**
- Container with space-around layout
- Clock scales with container: clamp(3rem, 60%, 6rem)
- Clock hands use percentages of clock size
- Time text uses rem units
**Location Widget:**
- Container flexbox with column layout
- Map background uses flex: 1 (was fixed 1.875rem)
- Map marker scales: clamp(1.5rem, 4vh, 3rem)
- Location text uses rem units
**2. Fix Attributes Widget Scrollbar (style.css)**
- Line 966: Change grid-auto-rows: 1fr to grid-auto-rows: minmax(0, 1fr)
- Allows rows to shrink below natural size to fit container
- Prevents overflow when widget manually positioned after auto-arrange
**3. Widget Size Constraints (widget files)**
- userAttributesWidget.js: Change minSize from {w:1, h:2} to {w:2, h:2}
- Enforces 2x2 minimum as requested
- Prevents cramped 1-column layout
- infoBoxWidgets.js: Change location minSize from {w:2, h:2} to {w:1, h:2}
- Allows narrow 1x2 layout for space-constrained dashboards
- Only widget that didn't fit on desktop screen
**Technical Details:**
- All info widgets now use rem units instead of vw for text
- Flexbox scaling ensures widgets fill their containers beautifully
- Percentage-based sizing for thermometer/clock internal elements
- clamp() used for min/preferred/max sizing across resolutions
- minmax(0, 1fr) fixes classic CSS grid overflow issue
**User-Reported Issues Fixed:**
✅ Info widgets scale to fill containers instead of fixed sizes
✅ Attributes widget no longer shows scrollbar in 2x2 (manual or auto-arranged)
✅ Location widget works in both 1x2 and 2x2 layouts
✅ All widgets maintain readability across different panel widths

Implements intelligent auto-layout system that efficiently arranges widgets to maximize space usage while respecting panel width constraints.
**Key Features:**
- Smart packing algorithm that sorts by widget area and finds optimal positions
- Respects responsive column count (2-4 columns based on panel width)
- Prefers full-width widgets when possible to eliminate gaps
- Fallback to narrower widths for better vertical packing
- Maintains minimum widget sizes
**Implementation:**
- GridEngine.autoLayout() - Core packing algorithm with collision detection
- DashboardManager.autoLayoutWidgets() - High-level API that re-renders after layout
- Auto-Arrange button in dashboard header (uses fa-table-cells-large icon)
- Event handler wired to call autoLayoutWidgets with preferFullWidth=true
**Algorithm Strategy:**
1. Sort widgets by area (largest first) for efficient packing
2. For each widget, try full-width placement first
3. Find first available position using row-by-row scan
4. If position is too far down, try narrower widths
5. Mark cells as occupied to prevent overlaps
**Testing Notes:**
- Works with current responsive column system (2-4 columns)
- Respects minimum sizes and column constraints
- Re-renders all widgets after repositioning
- Auto-saves layout changes
