Custom filtering rules ignored with DNS allowlist

**Issue description:**
With the latest version of AdGuard Home (0.104.3) custom filtering rules get ignored, if a matching DNS allowlist entry exists.

**Suggested solution:**
Please add an option to choose if custom filter rules or DNS list entries are prefered. Default behavior should be that custom filtering rules are always prefered.

**Example of issue:**
Blocked google.com only for specific clients, which worked until a DNS allowlist was added which whitelists google.com.

Custom filterung rule: ||google.com^$client='192.168.0.82'
DNS allowlist: https://raw.githubusercontent.com/notracking/hosts-blocklists-scripts/master/hostnames.whitelist.txt

**Result right now, which should not happen:**
