Make the DataTable's <thead> sticky so the column headers stay put at the
top of the page scroller while the rows scroll under them — the core of
'the table header should be fixed, only the rows scroll'. Benefits every
DataTable page (Channels manager, discovery, Audit log).
Each header cell gets bg-bg so rows don't show through; the header's
bottom border rides an inset box-shadow because a sticky <tr>'s own
border can scroll away with the collapsed table box. Verified on the
Audit log: 500 rows scroll under a header stuck at the scroller top; the
scroller's top fade is unobtrusive behind the solid header. Suite 15/15.
