This commit resolves 6 critical dashboard issues reported by user:
1. **Persistent px values causing 264rem widget heights**
- Root cause: state.js had hardcoded rowHeight: 80, gap: 12 (px)
- Root cause: index.js double-loaded layout, overwriting migration
- Fix: Changed state.js gridConfig to rem units (5, 0.75)
- Fix: Removed redundant applyDashboardConfig in index.js
- Fix: Added migration in layoutPersistence.js for old saves
- Dashboard now uses rem consistently throughout
2. **Auto-layout on first load**
- Added auto-layout in loadLayout() when no saved layout exists
- Prevents overlap from hardcoded default positions
- Saves auto-laid-out result as initial layout
3. **Reset layout causes overlap**
- Added auto-layout loop in resetLayout() after applying config
- Each tab auto-lays out to prevent widget overlap
4. **Auto-arrange loses inventory/social widgets**
- Fixed autoLayoutWidgets to gather ALL widgets from ALL tabs
- Previously only gathered current tab, lost other tabs
- Now always uses multi-tab distribution to preserve all widgets
5. **Auto-arrange leaves 2x2 gaps**
- Added compact pass in gridEngine.js after bin-packing
- Moves widgets upward to fill gaps
- Eliminates empty spaces at bottom of layout
6. **Tabs not compact (icon-only)**
- Updated tab styling: icons only, names show on hover
- Allows more tabs in compact space
- min-width: 2.5rem, larger icon size
Also added debug logging to track config values through initialization.
Fixes refresh sizing bug, reset overlap, widget loss, and layout gaps.
