Support Filtering Query Logs Using ECS IP Data

### Prerequisites

- [x] I have checked the [Wiki](https://github.com/AdguardTeam/AdGuardHome/wiki) and [Discussions](https://github.com/AdguardTeam/AdGuardHome/discussions) and found no answer

- [x] I have searched other issues and found no duplicates

- [x] I want to request a feature or enhancement and not ask a question

### The problem

Due to the limitation described in [issue #1727](https://github.com/AdguardTeam/AdGuardHome/issues/1727), it's not possible to see the ECS (EDNS Client Subnet) as a client when using AdGuard Home with OpenWRT in forwarding mode. This makes it impossible to search the query log by client IP.

### Proposed solution

I’d like to be able to search using ECS IP data that is already sent in DNS queries, to help filter client requests.

As shown in the image below, the ECS 192.168.1.38/32 appears in the request details:


However, I currently can’t find any results for 192.168.1.38 in the query log. With this feature, I would be able to locate all queries containing ECS 192.168.1.38.
