Add basic community structure (general/anonymous/topic) and features

[yulmwu]

The core concept of the Sesori project, the community, is composed of General(자유 게시판), Anonymous(익명 게시판), and Topic(토픽), which allows users to create their own communities based on specific subjects.

The features and characteristics of each board are as follows:

• General board – Only logged-in users can post; only the author can edit/delete; serves as the main board
• Anonymous board – Posting is allowed regardless of login status; user name and password are required when posting; IP is stored internally
• Topic – Community separation based on specific subjects; topics cannot be deleted; only the topic creator and administrators can modify them
• Topic Posts – Only logged-in users can post; only the author can edit/delete; must belong to a specific Topic

Topic List and Posts List support page-based pagination. For more details, refer to docs/RESTAPI/community.md etc.
