📝 Description

What changed?

• New "no matching result" empty state for search across ContentMapper, EntryMapper, and AssetMapper — added a shared MAPPER_SEARCH_EMPTY_STATE constant and wired v2Features={{ isNewEmptyState: true }} + a customEmptyState into all three mapper tables so a zero-result search shows a consistent centered empty state.
• Kept the table + search box mounted on 0 results (render guards now include searchText / searchContentType), so the user can clear the search instead of being stranded on the full-page empty state.
• EntryMapper: a no-match content-type search now keeps the selected content type and its entries instead of clearing the table.
• Refactored the asset mapper from infinite scroll to server-side pagination — replaced the fetch-1000-rows + itemStatusMap + loadMoreItems model with a single paginated fetchAssets({ skip, limit, seedSelection }) (same pattern as EntryMapper), added v2Features.pagination, rowPerPageOptions, and minBatchSizeToFetch.
• seedSelection preserves the user's in-progress selection across search / page changes.
• Removed the now-unused tableHeight prop from AssetMapper and calcHeight from entryAssetMapper.
• CSS fixes (index.scss): centered the search-empty state inside the venus .Table__centerWrapper; absolute-overlay centering for the field-mapper empty state; pinned the asset .Table height to remove the dead gap and keep the pagination bar + Save button visible; scoped the entry-mapper !important height rules with :not(.asset-mapper-container) so they stop overriding the asset table's sizing.
• Reverted local dev cmsType / localPath in upload-api/src/config/index.json back to placeholders.

Why?

Search on the mapper tables showed a bare/absent empty state and could trap the user with no way to clear the query. The asset table also used a heavy infinite-scroll fetch (up to 1000 rows at once) with layout bugs — dead space above the footer, clipped pagination bar, and a lost Save button. This standardizes the empty state, moves assets onto the same paginated model as entries, and fixes the associated layout issues.

🧪 How to Test

1. Run a delta migration (iteration 2+) to reach the Map Entry step (shows the Entries / Assets toggle).
2. On each mapper table (Map Content Fields, Map Entry → Entries, Map Entry → Assets), type a search query that matches nothing.
3. Clear the search and confirm the full list returns.
4. On the Assets tab: page through results, change rows-per-page (10/30/50/100), toggle selections across pages, then Save.

Expected result:

A centered "No matching result found" empty state renders with the search box still available to clear. The asset table paginates server-side, selections persist across page/search changes until Save, and the table + pagination bar + Save button are all visible with no dead gap or overlap.

👀 Reviewer Notes

• Asset mapper moved from infinite scroll to pagination — worth a close look at fetchAssets / fetchData and the seedSelection selection-preservation logic.
• Several CSS rules were scoped with :not(.asset-mapper-container) so entry-mapper !important heights stop fighting the asset table's venus-managed sizing — check both tables still size correctly.
