chore: bump .objectui-sha to e885db38d (Studio source-page editor fix) (#2476)

Pins the vendored @objectstack/console to objectui e885db38d so the served
console includes the Studio source-page editor (objectui #2109) — editing a
kind:'html'/'react' page now shows a code editor + live preview instead of
crashing on the design canvas. Range since the previous pin (998c5b3c9):
#2106 (data-table inline-edit error surfacing) + #2109 (the Studio fix).
