Enh: Mention the wishlist/vote system in the webadmin

[Axolotle]

Solution

• propose to remove criterias when no search results and criterias
  
• propose to add or vote for the app on the wishlist when no search results and no criterias
  
• propose to vote for the app with direct link to its catalog page if app is lowquality or lesser in AppInstall
  
  

PR STATUS

Ready
The current link to the wishlist includes the current webadmin's catalog search value but looks like the app wishlist cannot be queried with a search param.
