- Implemented the `/meta` command to fetch and display channel metadata including room ID, topic, message count, unique user count, estimated size, and protection level. - Added `ChannelMetaDto` to encapsulate channel metadata. - Updated `ChannelsController` to handle the new `/meta` endpoint. - Introduced `UploadLimits` configuration for admin-defined upload size limits for files, images, audio, and avatars. - Enhanced error handling and user feedback for metadata retrieval. - Updated documentation to reflect changes in encryption and room metadata. - Added tests for the new functionality and upload limits.
