Replace the stacked install modals (browse -> details -> import review)
with page-based flows so the primary action is always reachable:
- /manage/custom-widgets/workshop browses submissions as a card grid
with large previews, sitting in a tab next to the installed widgets
- /manage/custom-widgets/workshop/[id] merges the listing, security
review and source setup onto one page with a sticky install footer
- /manage/custom-widgets/publish/[id] replaces the publish modal
- /manage/workshop redirects; its navbar entry is gone
- the Custom CSS picker collapses from three modals to one
Extract useCustomWidgetImport and ImportReviewContent so the Workshop
page and the file/clipboard dialog share one import pipeline.
Votes now show the viewer's own choice filled Reddit-style, backed by a
new user-votes query, and screenshots get a zoomable lightbox.
Rework the installed list onto ManageCollectionItem: show the widget
description, replace the cryptic "JSX - 2" badge with plain request and
origin facts, and swap the toggle and bare pencil for a status badge,
a labelled Edit button and a menu entry for enable/disable.
Fixes found while reviewing:
- importing could run twice and duplicate a widget; guard on pending and
succeeded, and return to the installed list instead of the heavy edit
form
- a background refetch of the submission (window focus, or the
invalidation a vote triggers) reset the source setup and silently wiped
part-typed credentials; key the reset on the sources, not the object
- breadcrumbs raised MISSING_MESSAGE for unmapped dynamic segments; fall
back to the raw segment via t.has
- publishing had no in-flight guard and could post duplicate listings
- tooltips on disabled vote and report controls never fired, making the
sign-in hint unreachable
