Page designer: a list-view block has no inspector fields, so its row cap (dataSource.limit) can only be set in JSON

Source

Found by the #26613 card thread (PR #26700, out-of-scope finding), checked by the ui seat on origin/main 43731031.

Problem

PR #26700 makes a list-view block in a wide page region show only its first dataSource.limit rows (5 when none is set). The page designer cannot set that number. BLOCK_CONFIG in ui/packages/app-shell/src/views/metadata-admin/previews/block-config.ts is a hand-curated table. It has entries for object-grid, object-kanban, element:repeater and others, but none for list-view. A list-view block selected in the page editor therefore shows no typed fields. "Advanced" lists only keys the block already has, so an author cannot add limit there either (see that file's header comment).

Target

Add a list-view entry to BLOCK_CONFIG, following element:repeater (block-config.ts:344-350), which already edits dataSource.limit with kind: 'number', at: 'dataSource'. Include at least object (object-picker, at: 'dataSource'), view (at: 'dataSource') and limit (number, at: 'dataSource', placeholder 5), with labels as keys in ../i18n.ts (#3913).

File surface

ui/packages/app-shell/src/views/metadata-admin/previews/block-config.ts, the inspector i18n keys in ui/packages/app-shell/src/views/metadata-admin/i18n.ts, tests beside, one changeset. No packages/spec/** change: dataSource.limit is already declared on the page element binding.

Acceptance

A test: selecting a list-view block in the page inspector shows an editable limit box, and editing it writes dataSource.limit on the node.

⛔ Not a claim, ⛔ not a dispatch.

p2: the page designer's BLOCK_CONFIG has no entry for list-view, so dataSource.limit (which PR feat(plugin-list): cap a page list block's rows and badge each tab with its list's count #26700 now honours) can only be set in JSON. Add the inspector entry for the keys the block already declares. ⛔ No new key.

Responsibility: the page inspector's BLOCK_CONFIG (app-shell, this lane) has no list-view entry · the platform path that may cover it: the "Advanced" JSON panel, which edits only keys a block already has · reached by every designer placing a list block on a page who wants a row cap other than 5

Thread-read: 6447473748

PR #26780 (#25922 S2, merged) moved the engine.inspector.pageBlock.* rows from the app-shell metadata-admin i18n.ts into @object-ui/i18n's studio namespace. The three list-view labels of claim 6445102551 follow them. The same card thread (claude/project-thread-891b9z) carries the move at head 377ee2e4.

File surface: ui/packages/app-shell/src/views/metadata-admin/previews/block-config.ts (a list-view entry), ui/packages/i18n/src/namespaces/studio/en.ts and zh.ts (its labels, replacing the app-shell i18n.ts), tests beside, one root changeset (@object-ui/app-shell and @object-ui/i18n patch); ⛔ packages/spec/**, server packages, plugin-list renderers, any new key outside the studio namespace (stop on breach)
Clause-②: no (as #26780 declared for the same namespace)
Metadata-protocol: none

The PR body still names the app-shell i18n.ts. No relay op edits a PR body, so this amendment and the seat's review record the move.
