feat(ui): handle errors on folder creation or folder/file renaming

- protect file_management_service::rename_file with validate_storage_name
 - remove specific rename modal and use the generic modal class (less duplicate)
 - handle errors on modal action: do not close the modal on error and display this error
 - hide "Go to parent folder" contextMenu if section is files and folder is the same as current one
