pfSense

Configuring a Dynamic DNS Client for the DNS provider Gandi with a wildcard address record (e.g. "*.example.com", which is a valid DNS record of type A) does not validate the web form, error message : The hostname contains invalid characters.
The DNS provider Gandi supports that type of DNS record.
This problem is similar to the issue #9053.

The expected behavior is that a hostname with a wildcard character would be allowed, given that it's a perfectly valid DNS record for the DNS provider Gandi.

Additionnally, since the DNS provider Gandi was made available on pfSense (#9452), Gandi is currently transitionning to a new REST API and the former REST API (used in the commit edfe22f https://github.com/pfsense/pfsense/pull/4061/commits) will not be developed anymore according to this documentation : https://doc.livedns.gandi.net/ There will be no future developments on this API, as we are merging to our new REST api endpoint.
Changing the URL and the syntax of the authorization header could permit to query the new API, according to this documentation : https://api.gandi.net/docs/livedns/#v5-livedns-domains-fqdn-records.

I will create a Pull Request on GitHub to that effect.
