Data table headers on dashboard render two translations when changing language

When viewing the dashboard (Analytics) and changing the language, the data table headers show translations for both languages. Determine why the initial language translation is not removed.

The TAPi18n.getLanguage() method is reactive, meaning that it can be used to trigger template autorun() events.

However, the dashboard code may need significant refactoring in order to refresh the table (header) when language changes. I.e., the dashboard template only renders the charts on created(), and the chart rendering function is not designed to allow the table to be re-rendered separately.
