Follow Zeitwerk conventions in names with acronyms

We were getting a few errors when trying out Zeitwerk:

```
expected file lib/sms_api.rb to define constant SmsApi

expected file app/components/layout/common_html_attributes_component.rb
to define constant Layout::CommonHtmlAttributesComponent
```

In these cases, we aren't using an inflection because we also define the
`Verification::SmsController` and a few migrations containing `Html` in
their class name, and none of them would work if we defined the
inflection.

We were also getting an error regarding classes containing WYSIWYG in
its name:

```
NameError: uninitialized constant WYSIWYGSanitizer
Did you mean?  WysiwygSanitizer
```

In this case, adding the acronym is easier, since we never use "Wysiwyg"
in the code but we use "WYSIWYG" in many places.
