FilePermissionAspect implements DataHandlerCheckModifyAccessListHookInterface
`DataHandler` hook handling to avoid direct access to `sys_file` related entities:
- denies any write access to
sys_file(in datamap and cmdmap, unless it is an internal process) - denies any write access to
sys_filethat is on legacy storage - denies any write access to
sys_file_reference, referencing a file on legacy storage, or not part of the file-mounts of the corresponding user - denies any write access to
sys_file_metadata, referencing a file on legacy storage, or not part of the file-mounts of the corresponding user
