    fix(nacos): Add application key to consumer subscribe URL (#15872)
    
    * fix(nacos): Add application key to consumer subscribe URL
    
    Fixes #15843
    
    The subscriber URL constructed in NacosRegistry for the non-compatible mode 
was missing the application key, causing the application name to default to 
"unknown" in the Nacos client metadata. This commit adds the 
CommonConstants.APPLICATION_KEY parameter using the consumer URL's application 
name.
    
    * style: remove unnecessary comment in NacosRegistry
