Fixes #27905: Webapp complains that node-external-reports is missing a license, but it does not need one (and it doesn't complain)
https://issues.rudder.io/issues/27905
The webapp part that renders the notification is the PluginExpirationInfo.scala snippet, the problem is that it contains duplicate logic which should be the same as in the error-handling all defined in PluginError.scala (check expiration date, etc.)
The solution is to add constructors, and re-use validation from PluginError.scala.
Also, it's the opportunity for cleaning the snippets : PluginExpirationInfo and HealthcheckInfo contains dead code (for renderIcon).
