Steps to Reproduce

1. open ddns in Luci app

4. since the the domain should be url format, so i also tried %2A.xxx.yyy

 204145  CRIT : sanitize on domain found characters outside allowed subset - TERMINATE

I believe the parameter should be sth like:
"Domain":"xxx.yyy","Subdomain":"* (%2A if need url format)"
instead of
"Domain":"*.xxx.yyy","Subdomain":"*.xxx.yyy"

Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start at the ddns provider implementation for dnspod.cn-v3 and trace how the Domain and Subdomain values are built for the DescribeRecordList request. Reproduce with the configurations and curl output in the issue, then verify that wildcard domains pass sanitization and produce the expected Tencent Cloud API parameters.
