Fixed an issue where the Summary Bar could jump to the top of the page after scrolling and then resetting its position or resizing the browser window.

The Summary Bar now maintains its correct position during scrolling, position resets, and window resizing.

Improved action feedback throughout the extension:

✔ The Copy button now displays a visible “Copied” state.
✔ Successful submissions show a clearer green checkmark.
✔ Share, Copy and Send buttons now include subtle hover feedback.
✔ Disabled buttons no longer react visually.
✔ Includes minor Firefox compatibility improvements.
