Get one entity and its grounded mentions in a space
Returns `{ entity, mentions }` for a single entity in a space's graph. `entity` (or `null` if the id is unknown in this space) carries `id`, `type`, `name`, `key`. `mentions` are the grounded occurrences: each has `fileId`, `text`, and best-effort grounding — `page` + `bbox` (`{x,y,width,height}`) for documents, or `startSeconds`/`endSeconds`/`speaker` for audio transcripts (fields are `null` when not applicable). Requires `space:read` on `:spaceId`; missing access surfaces as a 404.
