fill filtered created date field value after page refresh

issue #1242

How to solve it

This is a quick fix, and I assumed that there is only one filter field called Created Date in the current situation. If there are more filter fields like the data grid table in the future, I think the best solution might be to control the filter column from the backend and include it in the response. 

Currently, columns are controlled in the kanban.blade.php file.

The response format from data grid table.

{
    "records": {
        "data": [
            {},
            {}
        ]
    },
    "columns": [
        {
            "index": "created_at",
            "label": "Created Date",
            "type": "date_range",
            "sortable": true,
            "filterable": true,
            "values": ["", ""]
        },
        {}
    ],
}

please apply a few changes to the Kanban blade

1. store search/side filters in a single variable
2. extract variable, make URL, and update search URI
3. call getLeads() without passing any params, just use old URL
4. check search/filters both should be compatible
5. test with pipeline also

The date-range component seems fine
