We were already using `find_by` most of the time.
Since there are false positives related to our `find_by_slug_or_id!` and
`find_by_manger_login` methods, which cannot be replaced with `find_by`,
I'm adding it indicating the "refactor" severity.
Although this translation has HTML, we aren't marking them as HTML safe
since we're using `I18n.t` instead of Rails' helper `t` method. So using
the `_html` suffix is counterintuitive in this case.
From now on these static pages:
`/privacy'
`/conditions'
`/accesibility'
`/help/faq'
`/welcome'
have been moved to the DB and can be modified easily by any
administrator in `/admin/site_customization/pages'
