Describe the bug

When deleting a certificate, the message is: Are you sure you want to delete this Certificate?.

When deleting a proxy host, the message is: Are you sure you want to delete this Proxy Host?.

It does not confirm the deletion for the specific deleted resource, and can lead to unwanted actions.

Nginx Proxy Manager Version
v2.13.5

Expected behavior
When deleting a certificate, the message should be: Are you sure you want to delete the Certificate named "www.example.com" ?.

When deleting a proxy host, the message should be: Are you sure you want to delete the Proxy Host which source is "www.example.com" and target is "https://app.local:443" ?.

and so on for all resources deletion.
