Action buttons in Puppet classes table have a poor styling
Description of problem:
The buttons in the puppet classes table are poorly formatted. The left/right padding is different and if a button is long enough, it overflows the cell/table
This only occurs for users without the `delete_puppetclasses` permission.
Steps to Reproduce:
1. Navigate to Configure -> Classes
2. Observe the actions column
Consistent padding, buttons not escaping from their cells
