feat(views): saved-views backend — table, model, CRUD + reorder API

Per-user named snapshots of the feed's FeedFilters. New saved_views table (migration 0035, unique per user+name, position, is_default) + SavedView model, and a /api/saved-views router (list/create/patch/delete/reorder) gated behind require_human so the shared demo account can't pollute it. Setting is_default clears the flag on the user's other views (one default).

+Create Date: 2026-07-01
+
+Adds the `saved_views` table: per-user named snapshots of the feed's filter/sort state. Each
+row stores the serialized FeedFilters (JSON), a sidebar `position` for drag-reorder, and an
+`is_default` flag (at most one per user, enforced by the API) for the view applied on load.
