Fixed "Cannot read properties of undefined (reading 'update')" errors
caused by chart setTimeout callbacks persisting across Turbolinks page
navigations.
Changes:
- Add existence checks before initializing charts
- Guard all .update() calls with element and instance checks
- Track all setTimeout IDs in chartTimeouts array
- Clear timeouts on Turbolinks navigation events
- Clear timeouts at start of pieChartHome() to prevent duplicates
This ensures chart update callbacks only run when chart elements exist
on the page, preventing errors when navigating to pages without charts.

Fixed critical issues causing JavaScript errors on dashboard pages:
## Problems Fixed
1. **jQuery not defined ($)**
- jQuery was loading AFTER application.js
- Scripts in dashboard/home tried to use $ before it was available
- Error: "Uncaught ReferenceError: $ is not defined"
2. **Turbolinks conflict**
- Changed data-turbo-track but app still uses turbolinks gem
- Error: "Cannot set properties of undefined (setting 'Turbolinks')"
- Both turbolinks and turbo-rails in Gemfile causing conflicts
3. **type="module" breaking globals**
- ES6 modules have their own scope
- Prevented jQuery from being global window.$
- Broke all existing jQuery-dependent code
## Solutions Applied
1. **Script Load Order**
```html
<!-- BEFORE: Wrong order -->
<%= javascript_include_tag "application" %>
<script src="jquery.min.js"></script>
<!-- AFTER: Correct order -->
<script src="jquery.min.js"></script>
<%= javascript_include_tag "application" %>
<script src="bootstrap.bundle.min.js"></script>
```
2. **Reverted to Turbolinks**
```erb
<!-- Changed back from: -->
"data-turbo-track": "reload"
<!-- To original: -->
"data-turbolinks-track" => "reload"
```
3. **Removed type="module"**
```html
<!-- Before: -->
<%= javascript_include_tag "application", type: "module" %>
<!-- After: -->
<%= javascript_include_tag "application" %>
```
## Technical Details
**Script execution order:**
1. jQuery (CDN) - Makes $ available globally
2. Bootstrap CSS (CDN) - Styles load early
3. application.css (Rails) - Custom styles
4. application.js (Rails) - Can now use jQuery
5. Bootstrap JS (CDN) - Needs jQuery, loaded last
**Why this order matters:**
- application.js likely has jQuery dependencies
- Dashboard charts/graphs use jQuery
- Bootstrap 5 JS doesn't require jQuery but loads after for safety
- Turbolinks needs to initialize before page interactions
**Compatibility:**
- Keeps existing jQuery-dependent code working
- Maintains Turbolinks behavior (app has both gems)
- All dashboard statistics/charts now load correctly
- No breaking changes to existing pages
This maintains backward compatibility while preserving the modern UI.
