Move handler media access behind a store interface Define the media and comment types that handlers consume and expand the handler store interface to include media entry and comment reads. This removes the server's direct dependency on little_moments.Metadata. Add a store/memory adapter that converts imported metadata into the handler-facing store shape while delegating visit counters to the existing visit store. Wire cmd/app to compose the sqlite visit store with the memory adapter before constructing handlers.
