Split action icons into their own columns, tighten spacing, no crosshair

Link and edit icons get one dedicated column each instead of sharing
one text-align: center cell -- with a shared cell, a row with only the
edit icon (non-linkable types) centered differently than a row with
both icons, so pencils never lined up vertically across rows.
Separate columns line up by construction. Verified: identical left
offset (141px) for the edit icon across 15 consecutive rows.

Also: tighter cell padding (was using the table's default 0.6rem
horizontal padding, way more than an icon needs) and no column-hover
crosshair on these technical columns -- nothing meaningful to compare
across rows there.
