Update CMS client configuration and refactor content organization

The code changes involve a significant update to the configuration of our CMS client. The nature of retrieving content items has been refactored to be more granular, allowing for the identification and fetching of content from specified collections rather than general categories. These modifications improve the efficiency and specificity of content queries. Furthermore, other changes were made to provide a better alignment of our content structure, including the reorganization of content files and renaming of image paths in various components for consistency.
