catarrh ded63c94e4 v3.32.6: the empty preset banner no longer flashes on the RAM view
ramOpChanged() (v3.28.0) un-hid #ram-preset-warning by the operation
kind, but the banner's text and visibility belong to
spPresetWarningRender() (which already suppresses it for the batch
ops).  With no warning text the empty amber box stayed visible until
the next status poll re-hid it - a flash on every RAM view / operation
switch.  The visibility is content-driven again: the setHidden line is
gone and the renderer is called.

Pinned in frontend/tests/ram.test.js with the real renderer (the
pre-fix code fails the test).  1016 Python + 954 frontend green;
simple-v464.
