ppai: fix lint errors (#7788)

* ppai: fix lint errors

* go back to typing Dict and Tuple

* update beam and substitute Self type with a type variable

* use List instead of list

* import beam explicitly inside function

* import beam explicitly inside function

* fallback to a mock prediction if the model is not found

* more error handling

* define deployed_model_id

* define deployed_model_id

* make deployed_model_id numeric

* better error handling
