Exclude full_content from stream list API responses

The /stream endpoint now skips selecting full_content and header_image
from the database, reducing memory allocation and response payload size
for list views. Full content remains available via /item/:id endpoint.

Adds omitempty to JSON tags so empty fields are omitted from responses,
and a test verifying full_content is excluded from stream responses.
