"Aliases" screen improvements

Now that it's possible to import hundreds of aliases, navigating them in the dashboard is a bit difficult. At the moment, you can only move one page at a time. It would be helpful to allow quicker navigation, e.g., jumping directly to the last page or showing a few page options ahead.
Currently, aliases can only be deleted one at a time. I think It would be useful to add a selection option so multiple aliases can be deleted at once.

Bumping up!
I had to delete several aliases one by one multiple times while testing custom alias validation 😅
