Ken Johnson 8abf409041 Fix Google Charts loading for AJAX-loaded bar graph ...

The issue was that google.load() doesn't work reliably when called
from AJAX-loaded content. The callback wasn't firing.

Solution:
- Load Google Charts library once in main application.html.erb layout
- Bar graph partial now just polls for google.visualization to be ready
- Uses retry logic (50 attempts @ 100ms = 5 second timeout)
- Returns success/failure boolean for proper flow control
- Removed duplicate script loading from partial

This ensures Google Charts is available globally for all chart views
(bar graphs, pie charts, performance charts) without timing issues.
