[Feature Request] mDNS support for Account URLs

[StevenLares]

This page explains mDNS

I have a server in my home network that's running FreshRSS. Let's say that the server's host name is home-server

I wish to add this FreshRSS instance to Readrop v2.0-beta-1 by going to Account > New Account > FreshRSS

Then, I enter http://home-server:freshrss_port under "Account URL"

However, when I click "Validate", I get an error message:

Input is not a valid URL

Instead, I must use http://local_IP:freshrss_port or http://home-server.local:freshrss_port Note the use of .local in the second option.

Some reasons why adding mDNS support would be useful:

1. No need to remember the server's local IP
2. Tailscale users can connect to their home servers by using the same mDNS hostnames available in their local network. This extends to their FreshRSS instances.

In other words, if I can set Account URL to http://home-server:freshrss_port, then I can connect to FreshRSS while away from home (using Tailscale).

When I get back home and directly connect to the network, I can continue to use the same RSS server seamlessly (without having to manually adjust the Account URL).
