fix: chat_msg media_dir path — strip filename from g_cc.db_path

g_cc.db_path is '/data/.../files/chats.db' (file path), but media blocks
are written to '/data/.../files/media/<channel>/'. chat_msg was concatenating
'chats.db/media/...' — now strips the database filename, using only the
directory portion for the media path.
