Implement validation for all prod models

Labels: enhancement, Impact: High, Work: Medium

Note For Contributors

• For any validation job you implement, the corresponding domain object of the prod model should be updated to do the following in the same PR:
  • Instead of throwing errors using utils.ValidationError("some message"), they should throw typed errors for each message category.
  • These error types should be defined in a new file as per the following example:
    • Domain class: class Exploration, file: exp_domain.py
    • Error class: class ExplorationDomainError(utils.ValidationError), file: exp_domain_errors.py

• Implement validation jobs for all prod storage models. This includes implementing a base job first for a particular subest of models inheriting from the same base model and then using it as the super class for other validation jobs.

  • BaseModel & sub-classes: Tracked in https://github.com/oppia/oppia/issues/21869. Note that, the base models listed below also inherit from BaseModel but are expected to serve as base for other storage models and hence a separate base validation job should exist for them which will act as the super class for validation jobs of all other storage models which inherit from the respective base model.

• Implement any missing domain layer validation for all domain objects corresponding to these prod models. For more details, on what goes in a validation job vs domain layer validation check out this doc.
