[FIX] web: center ONLY o_cp_action_menus div

The commit 590d0ca8 tried to center the o_cp_actions_menu but instead it
was spreading every direct child of the o_cp_bottom_left zone.

This commit puts the bottom left zone back to a left aligned flex layout
and puts an automatic left margin on the actions menu zone.
