Get Shared Project Enrichments

Get enrichment metadata for a shared project (slim, read-only).

Returns only the fields needed for column mapping (id, name, layer_id, is_data_source, dtype). Excludes sensitive fields like params, tool, and description. Enrichments on share-restricted (parcel) layers are dropped — the layer is hidden, so its enrichment metadata must be too.

Args: share: Validated ProjectShare from token enrichment_repo: Repository for fetching enrichment data layer_service: Service resolving which layers are share-restricted

Returns: Slim enrichment metadata for visible enrichments on non-restricted layers
