What did you do?

Clean up task

• co-locate all the components that are only used on the Journey page to ui/src/views/JourneyPage/
• Several place we used logic A + B + C to render a translatable string. That is not really allowed and makes translation difficult. Most of these are now markdown strings like "Registration deadline is **{date}**, *{days}*." Referenced like:

          <mark-down
            :content="
              $t('absenteeRequestDeadline', {
                date: niceDate(info.mail_in.request_deadline),
                days: daysLeft(info.mail_in.request_deadline),
              })
            "
          />

• Absentee page showed

  Registration deadline is Oct 28, 2022, in 32 days

  But should say

  Deadline to request your absentee ballot is Oct 28, 2022, in 32 days.

• Removed unused code from ballot drop off page
