Bug 32503: (follow-up) Move data-order attributes

It looks like the data-order attributes were at the wrong level to me,
i.e. not part of the 'td' but instead part of the cell content.

This patch moves those data-order attributes where possible and drops
the data-type definitions on the headers.

However, for the cancellation case, this isn't as clear cut as we may
well display more than one cancellation request date in the same cell.
For this case I've left Katrins data-type="@data-order" trick.
