Make timebox message translatable with flexible variable order

Currently, the timebox dialog message is built from two separate strings,
each containing one variable:
"{ $count } cards studied in" + "{ $count } minutes."

As a result, translators cannot freely reorder the variables in their translations.

This change introduces a single string with both variables, allowing translators
to adjust the order for more natural expressions in their languages.
