fix: prevent dashboard action menu scrolling

[syedgalib]

Summary

• reserve enough vertical space in the user dashboard listing table for action dropdowns when only a few listings are displayed
• keep the last action dropdown opening downward for one-to-three-row result sets so it uses the reserved space instead of being positioned above the scroll wrapper
• rebuild the committed public LTR and RTL CSS assets

Root cause

The responsive listing table owns horizontal overflow, which also makes it the vertical scroll container. With a short result set, a dropdown could extend outside that container. The existing last-row rule also opened the menu upward even when there were too few preceding rows to contain it.
