We have the `# frozen_string_literal: true` comment on all our
files. This means all string literals are frozen. There is no need
to call #freeze on any literals.
For files with `# frozen_string_literal: true`
```
puts %w{a b}[0].frozen?
=> true
puts "hi".frozen?
=> true
puts "a #{1} b".frozen?
=> true
puts ("a " + "b").frozen?
=> false
puts (-("a " + "b")).frozen?
=> true
```

* Fix user title logic when badge name customized
* Fix an issue where a user's title was not considered a badge granted title when the user used a badge for their title and the badge name was customized. this affected the effectiveness of revoke_ungranted_titles! which only operates on badge_granted_titles.
* When a user's title is set now it is considered a badge_granted_title if the badge name OR the badge custom name from TranslationOverride is the same as the title
* When a user's badge is revoked we now also revoke their title if the user's title matches the badge name OR the badge custom name from TranslationOverride
* Add a user history log when the title is revoked to remove confusion about why titles are revoked
* Add granted_title_badge_id to user_profile, now when we set badge_granted_title on a user profile when updating a user's title based on a badge, we also remember which badge matched the title
* When badge name (or custom text) changes update titles of users in a background job
* When the name of a badge changes, or in the case of system badges when their custom translation text changes, then we need to update the title of all corresponding users who have a badge_granted_title and matching granted_title_badge_id. In the case of system badges we need to first get the proper badge ID based on the translation key e.g. badges.regular.name
* Add migration to backfill all granted_title_badge_ids for both normal badge name titles and titles using custom badge text.
