MDL-35078 enrol: allow times to be chose on bulk enrolment forms
MDL-35078 enrol: allow times to be chose on bulk enrolment forms

Previously only a date was available, which made it ambigious whether
the the enrolment was inclusive of the date. Now we use a time to make
it less ambigious.

This matches changes done in other forms in MDL-41173.
