[typing] Validate all calls using `pydantic.validate_call()` decorator

[ns-rse]

Further to #1299 / #516 and related Pull Requests (#1311) we can improve type-checking and usage by using the Pydantic Validation Decorator (@validate_call() which checks the arguments data types are valid (i.e. the correct type) before the function is executed.

May wish to consider using Field() (see bottom of documentation page) to validate ranges of values in some instances.

Yes! Please! I've been using this in my side project and it's good.
