Use the term "Project Tags" more consistently

Summary:
Add some more consistency between the terms "project", "tag", hashtag, "slug".
And also between "assign to" vs "add related" vs "associated with" vs "tagged with".

This might not be the perfect color for the bikeshed but feels a bit better.

Closes T15546
Closes T15701

Test Plan: Grep the code, go through about 500 results, check in which context the relevant ones are used (to not rename repository tags, for example).
