Widgets are no longer hand-wired per-feature across scheduler.ts, settings.ts, and the API routes. A new WidgetPlugin interface (backend/src/widgets/types.ts) lets a widget declare its own schema migration, poll interval, routes, and uninstall hook; an installed_widgets registry table replaces the closed widgets/widgetOrder unions on global_settings, and the scheduler/route registration now iterate loaded widgets generically instead of one hardcoded block per widget. PoE2 moves into backend/src/widgets/poe2/ as the first real plugin (its tables renamed to the widget_poe2_ convention, league cache moved into a new generic widget_kv store). Weather/Stocks/Bookmarks get thin wrapper plugins so they share the same dispatch loop without migrating their schema. New admin routes let a widget be uploaded live (POST /api/admin/widgets, JSON body with inline file contents — no archive dependency needed) and removed with full data pruning (DELETE /api/admin/widgets/:id): a host-side safety-net sweep drops any widget_<id>_* table and widget_kv rows regardless of whether the widget's own uninstall() hook runs, so deleted widgets don't leave dead data behind. Built-in widgets can't be deleted through this route. Verified against a copy of the real dev DB: old poe2_watchlist data survives the rename, the migration is idempotent on a second boot, and a live-uploaded test widget was polled, queried, and fully deleted (table/kv/on-disk directory all gone) without a restart.
