Prefer prefetching keys (#9289)
magical black-box key retrieval is slow, due to needing to repeatedly resolve (and potentially decrypt) keys. Doing the work up front is both more explicit and much faster.

It would be preferable to move OrganizationId to an opaque type in the models, but that has rippling effects all over the place and ultimately is stopped by vault filtering on strings rather than ids, but still calling the property `organizationId`, we need to fix that first.
