fix: remove t from getDefaultAppState and allow name to be nullable (#7666)

* fix: remove t and allow name to be nullable

* pass name as required prop

* remove Unnamed

* pass name to excalidrawPlus as well for better type safe

* render once we have excalidrawAPI to avoid defaulting

* rename `getAppName` -> `getName` (temporary)

* stop preventing editing filenames when `props.name` supplied

* keep `name` as optional param for export functions

* keep `appState.name` on `props.name` state separate

* fix lint

* assertive first

* fix lint

* Add TODO
