Accept only one column layout when importing registrations

Recognizing several spellings of each header, falling back to reading the
columns positionally, and accepting five date formats made the code - and the
error messages - far bigger than the flexibility was worth. The file must now
have the columns `username, name, card_number, date`, in that order, and dates
must be written as YYYY-MM-DD.
