Summary

• Prevent dashboard tab clicks from triggering native hash scrolling.
• Preserve hash-based deep linking for dashboard tabs.
• Update the dashboard URL hash with History API without moving the page scroll position.
• Use the clicked tab link consistently so nested icon/text clicks behave correctly.

Testing

• Confirmed changed files are limited to dashboard tab logic:
  • assets/src/js/public/lib/dashTab.js
  • assets/js/directorist-dashboard.js
• Manual browser testing should verify tab clicks, refresh with hash URLs, and sidebar/mobile dashboard navigation.
