refactor: adjust layout dimensions for consistent width and height

### Changes:
1. **Hero Section Layout** (commonHome.tsx)
   - Changed `lg:items-start` → `lg:items-stretch` for equal height alignment
   - Added `min-h-full` to hero content column for full height
   - Ensures Sidebar height matches ProductMatrix height

2. **Content Section Layout** (commonHome.tsx)
   - When Sidebar present, uses matching grid structure from hero section
   - Grid: `grid-cols-[minmax(0,1fr)_360px]` (same as hero)
   - Content slots span full width with hidden spacer for visual balance
   - CommunityFeed now matches total width of (ProductMatrix + Sidebar)

3. **Sidebar Component** (Sidebar.tsx)
   - Added `h-full` and `flex flex-col` for full height support
   - Maintains sticky positioning while filling available space

4. **HomepageLanding** (page.tsx)
   - Applied same height adjustment: `lg:items-stretch` + `min-h-full`
   - Consistent with template version layout

### Result:
- Sidebar height = Hero section height (full height alignment)
- CommunityFeed width = ProductMatrix width + Sidebar width
- Visual consistency across hero and content sections
- Both homepage versions (template and direct) have identical layout
