📔 Objective

Fix a translation bug affecting Chrome browser.

Chrome removes invalid interpolation keys in its messages.json translations. This caused the generator on chromium browsers to render !@#$%^&* as !@#^&*. Unfortunately, the I18nService used by the web and desktop code renders $$ when properly escaping the i18n string. Thus, the solution is to hard-code the value.

Angular string interpolation is used as the fix because the entity escape sequence for @ looks like line noise.

This PR also removes unused translation keys as to avoid confusion in the future.

Fun fact: we can't localize this text because the i18n method used by the browser doesn't match the implementation used by web. This needs to be hard-coded in the view.
