Improve Static Type Checking And Annotations Across the Codebase

Summary

Improve static type checking across the codebase to support better integration with the OpenLIFU-app, which sometimes leverages type hints for automating GUI elements.

Motivation

Incomplete or inaccurate typing (e.g., raw dict/list usage, incorrect assignments, missing annotations) can lead to unintended behavior or reduced ability to automate generation of GUI elements for modifying openlifu classes.

Scope

This issue serves as a tracker for PRs that:

• Add missing or more precise type annotations
• Fix type mismatches
• Replace untyped or loosely typed structures
• Improve overall type inference and clarity

Traceability Information:

• Issue: OpenLIFU-python#262
• SOFTREQ: OpenLIFU-python#337
• Comment: This issue is related to the requirements defined in OpenLIFU-python#337.

Start with the scope in issue #262 and read the related requirement in issue #337. Identify a specific typing gap in the Python codebase before beginning; done would mean a focused change that adds or corrects annotations, improves type inference, or resolves a type mismatch with suitable validation.
