style(shared-tags): apply table-actions class so row icons render horizontally

The edit and delete icons in the tag-management dialog were stacking
vertically: the wrapper <div> had no flex styling so the two mat-icon-buttons
wrapped to two rows even though the column had room for them side-by-side.

The colocated SCSS already defined `.table-actions { display: flex; gap: 4px; }`
but the class was never applied. Adding it gives the existing rule something
to bind to.
