feat(reports): move generated time to the footer and name standard thicknesses

The generated date sat among the summary's report details and printed a UTC
offset nobody on the shop floor reads. It now goes in every page's footer,
left of "Page X of Y", in the computer's own time zone without the offset.

The thickness now leads with its gauge or plate fraction ("16 ga - 0.0598 in")
when it matches one, as the thickness box lists it. Reporting references Core
only, so the desktop looks the name up in StandardThicknesses and passes it on
the snapshot.
