Fix dropdown clipping: use fixed positioning to escape overflow

UserActionsMenu and SnoozeDropdown were clipped by parent containers
with overflow-x-auto/overflow-y-auto. Switch from absolute to fixed
positioning — compute viewport-relative coordinates on open via
getBoundingClientRect. Dropdowns now render above all overflow
boundaries.
