Question: min_date / max_date

Hey!
Thank you very much for your project. It looks fantastic and is really pleasant to use.

I have a question about the filters. When I open a [dashboard](https://clickpy.clickhouse.com/dashboard/apache-airflow) without any filters, the default values are applied automatically, which makes sense.

If I open a dashboard using a [link](https://clickpy.clickhouse.com/dashboard/apache-airflow?min_date=2025-03-22&max_date=2026-06-20) with both `min_date` and `max_date` query parameters, the data is correctly limited to that interval.

However, if I provide only `min_date`, the value shown in the filter is replaced with [2011-01-01](https://clickpy.clickhouse.com/dashboard/apache-airflow?min_date=2025-03-22), while `max_date` is automatically set to today's date. It seems like `min_date` should not be overwritten and should instead use the value provided in the query parameter.

Is this the expected behavior?

Thanks! ❤️

Open the Apache Airflow dashboard linked in the issue, first with both date parameters and then with only min_date, and compare the filter values. Read the dashboard’s query-parameter handling and date-filter defaults; the issue does not name a file or test. Done would mean confirming the expected behavior and ensuring a supplied min_date is retained when max_date is omitted.
