Replace broken Google Charts with modern table and stat cards

Browse Source 
The deprecated Google JSAPI (google.load) was failing to load reliably,
causing the bar graph view to timeout after 5 seconds. Google Charts
with the old jsapi has been deprecated and has timing/loading issues,
especially with AJAX and Turbolinks.

Solution:
- Replaced bar chart with clean, modern table showing same data
- Added colorful stat summary cards with totals
- Removed unreliable Google Charts library from layout
- No JavaScript dependencies or loading delays
- Instant rendering, works perfectly with AJAX loading

The new view:
- Clean responsive table with hover effects
- 4 summary cards showing total visitors, orders, income, expenses
- Color-coded borders matching original chart colors
- Modern card design consistent with rest of the app
- Works immediately without any loading or timing issues

Note: Pie charts and performance charts still use their own
Google Charts loading, which works in their specific context.
