Change video storage directory from /storage to /mnt/nfs_share

- Update StorageConfig default base_path in core/config.py
- Update base_path and camera storage_paths in config.json and config.compose.json
- Update Docker Compose volume mounts to use /mnt/nfs_share
- Update start_system.sh to create /mnt/nfs_share directory
- Update convert_avi_to_mp4.sh to use new NFS path
- Update all documentation files to reflect new storage paths
- Videos now stored on NFS server at 192.168.1.249:/mnt/nfs_share/
