[nextjs]SNS Server-9(myapp19)

👉🏻 inbox_posts 테이블에 actor와 original_id필드를 추가 합니다.
Add the actor and original_id fields to the inbox_posts table.

👉🏻 original_id필드는 나중에 id(API의 id 부분)를 짧게 변환하기 위해서 만든 필드입니다.
The original_id field was created to store a shortened version of the id (the ID portion of the API) for later use.

👉🏻 Actor는 글 보낸 사람의 전체 URL입니다.
“Actor” is the full URL of the person who sent the post.

👉🏻 기존의 타임라인 UI부분의 주소에 @userid를 사용합니다.
Use @userid in the URL for the existing timeline UI section.
