style: fix Python formatting for black 26.x (#4644)

## Summary

Fix Python code formatting to comply with black 26.x which has new
formatting rules.

## Changes

- Reformatted 14 Python files to comply with black 26.x
- Main changes involve multi-line function calls and textwrap.dedent()
formatting

## Motivation

This fixes the CI Python format check failures that are blocking all
PRs, including #4625.

The CI installs black 26.x which has stricter/different formatting rules
than previous versions. These formatting issues exist in the main branch
and are not introduced by any specific PR.

## Test

- [x] Run `python3 -m black --check .` locally - passes
- [x] Run `python3 -m isort --check .` locally - passes
