Add comments to notes detail pages.

 ### Core primitives every module gets
 
 - **Entity registry.** Modules declare entity types; share-link, activity log, search, reminders all work against any registered entity.
-- **Dashboard widget registry.** Every widget is uniformly configurable (no singleton/parameterized split) and reusable — each placement on a dashboard is an independent instance with its own config. Each user has multiple dashboards; the active dashboard composes whatever widgets they've placed.
+- **Dashboard widget registry.** Every widget is uniformly configurable (no singleton/parameterized split) and reusable — each placement on a dashboard is an independent instance with its own config. Each user has multiple dashboards; the active dashboard composes whatever widgets they've placed. **Edit mode** (`?edit=1`) must pre-render live widget content (task 81): server-side `DashboardWidgetContent` per placement, keyed by index in `widgetContents`; `render` loads real data; never show meta-description placeholders for saved placements.
 - **Quick-add registry.** Modules register quick actions for the dashboard's `+` menu.
 - **Share-link service.** `createShareLink(entityType, entityId, { expiresAt, capabilities })` → `fam.ginnoir.com/s/<token>`. Generic.
 - **Notification bus.** `notify(userId, { title, body, url })` fans out to web push + in-app + (optional) ntfy.
