Add Hagezi’s “Encrypted DNS Servers Only” list to AdGuard DNS as a separate option

### Issue Details

Hi there — I wanted to suggest adding the 📤 Encrypted DNS Servers Only blocklist from Hagezi as an optional filter in AdGuard DNS.

Right now, AdGuard includes the full DoH/VPN/TOR/Proxy list from Hagezi, which is great for blocking a wide range of anonymizers — but it’s a bit too broad in some cases.

Here’s the issue:
If I want to block encrypted DNS (like DoH or DoT) but still use a browser VPN extension (like Surfshark, NordVPN, or Browsec), I have to go into my AdGuard DNS dashboard and turn off the entire DoH/VPN/TOR/Proxy blocklist. That ends up allowing a lot more than I want — just so I can get a browser VPN working.

### Proposed solution

If AdGuard offered the Encrypted DNS Servers Only list as a separate option, it would give users a nice middle ground:

Block encrypted DNS services to make sure the system uses the DNS I want

Still allow VPN extensions or proxies in the browser

No need to disable broader protections just to make a single extension work

It’s already a maintained list by Hagezi, just like the others. Would be awesome to have this as a standalone toggle inside AdGuard DNS.
