Enhance Tab Functionality for URL Query-Based Field Filtering

[Ehco1996]

Summary:

This PR introduces improvements to the tab functionality, allowing tabs to serve as quick filters for field data based on URL query parameters. The current logic does not handle this scenario correctly, leading to incorrect filtering results.

Example:

Currently, the tabs are structured as follows:

tabs = [
    {
        "models": [
            "group1",
        ],
        "items": [
            {"title": "group-1", "link": "/admin/app_name/group/"},
            {"title": "group--2", "link": "/admin/app_name/group/?lable=online"},
        ],
    },
]

This PR addresses the issue by implementing a more robust logic to correctly interpret and apply the URL query parameters for filtering.

Would you mind to upload a short video what does this functionality do?

Please find the GIF attached. Please note that all tabs correspond to the same model, but with different filter parameters, as mentioned in the PR description.

code looks like

[
    {
        "models": [
            "proxy.proxynode",
        ],
        "items": [
            {"title": "所有", "link": "/admin/proxy/proxynode/"},
            {"title": "美国", "link": "/admin/proxy/proxynode/?country__exact=US"},
            {"title": "日本", "link": "/admin/proxy/proxynode/?country__exact=JP"},
            {"title": "香港", "link": "/admin/proxy/proxynode/?country__exact=HK"},
        ],
    }
]

Nice. I used it for a link in settings.py -> SIDEBAR -> navigation:
"link": lambda request: reverse_lazy("admin:rezeptor_prescriptionsync_changelist") + "?kassenrezept=true&status__exact=processing
which now does not collapse anymore but stays open & active.
Now I don't need to create a proxy for Model.
Thank you

I think, the @pnost solution is correct. You don't need to change any business logic to get tabs with filters.

[pnost]

@lukasvinclav it's not only about having tabs with filters but having them hightlighted as active tab.
Links in tabs and navigation are not highlighted as active until now if you use the same model but add a filter to the url. @Ehco1996 commit changes this.
