Feature Request: Add "Report Element" Option via Context Menu in Safari Extension

## Summary
I'd like to suggest a feature for AdGuard's Safari extension: the ability to right-click and report ads, trackers, or unwanted elements directly from a web page. This would make it much easier for users to report issues without having to go through additional steps.

## Use Case
Right now, reporting ads or trackers usually requires users to identify and report them manually, often outside the browser. With this feature, users could:
1. Right-click on the element they want to report (like an ad or a tracker).
2. Choose a new "Report this element" option in the right-click menu.
3. Fill out a quick form (optional) that captures details like what the element is, what the issue is, and submit it, while staying on the same page.
4. Receive a confirmation that their report was sent.

This would make the reporting process faster and easier, allowing users to help improve AdGuard's filters without interrupting their browsing.

## Why It Would Help
- It simplifies the reporting process. Users won’t have to leave the page or open a separate app to report ads or trackers.
- More accurate reports. Users will be able to immediately report the exact element causing issues.
- Encourages more user participation in improving filters, since the process becomes less of a hassle.
