feat(dashboard): wire EnrichmentBlock between Resume strip and Mission Control

Dashboard loader fetches /api/documents/incomplete?size=5 plus the
existing /incomplete-count and surfaces both via data; +page.svelte
renders EnrichmentBlock with the top 5 docs, the total count, and the
bannerCount state bound to DropZone's onUploadComplete callback
(issue #296).

The block returns null when there is nothing to show, so dashboards
without pending uploads stay uncluttered.
