Fix policy drawer title being too long

What does this MR do and why?

Describe in detail what your merge request does and why.

Fix policy drawer title being too long

• when the policy title is too long in the drawer, it is truncated
• the truncated string pushes the dismiss button off the view making it impossible to close the drawer
• limit the length of the title
• the titles still have tooltips associated with them

Changelog: fixed

EE: true

How to set up and validate locally

1. Upload a GitLab Ultimate license
