Eliminate horizontal scroll across the full width…

Details

The widget tooltip-overflow clip was gated at <=700px, so tablets and
narrow desktops (701-960px) still scrolled sideways (~82px at 768).
Ungate the overflow-x:clip on the TPP/EDCR columns so it applies at all
widths, and bound the shared data-tip tooltip width so it can't inflate
scrollWidth anywhere. Also fix the 320px project-grid blowout
(minmax(0,1fr)/min-width:0) and the hero proof-stats overflow. Validated
scrollWidth <= innerWidth at every width 320-2560.
