feat: update BGP community structure and related documentation. Refactor BGP community handling by renaming fields from 'name' and 'kind' to 'community' and 'title' across the codebase. Update OpenAPI specifications, database interactions, and UI components to reflect these changes, enhancing clarity and consistency in community management.
