Pull Request Overview

This PR fixes type hint inconsistencies across multiple files by updating Tuple type annotations to use variable-length syntax (Tuple[type, ...]) where parameters accept tuples of arbitrary length. This addresses issues similar to #4806 where fixed-length tuple annotations were incorrectly used for parameters that should accept variable-length tuples.

Key changes:

• Updated type hints from Tuple[str] to Tuple[str, ...] for block type parameters
• Updated type hints from Tuple[int] to Tuple[int, ...] for channel configuration parameters
• Fixed one incorrect annotation from Tuple[str] to str for a non-tuple parameter
