Metadata API
The metadata branch (/metadata/{tenant}) serves the resolved presentation metadata for a tenant — the dashboards, layouts, and per-type descriptions that tell a client how to render objects. Unlike the data branch it returns shape and configuration, not object values.
Endpoints referenced elsewhere in the docs include the object dashboard (GET /metadata/{tenant}/dataObject?types={...}) and the class dashboard (GET /metadata/{tenant}/dashboard/{type}) — see Archetypes › Publication on dashboards and Layouts.
This page is a stub. Enumerate the MetadataController endpoints and document each: dashboards, layouts, resolved type metadata, and how the published shapes (ClientLayoutItemView, ClientArchetype, etc.) relate to the model. Also cover /systemMetadata if it belongs here.
