Reformat with black 26.1.0

[Copilot]

Reformatted codebase with black 26.1.0 to pass linting checks.

Changes

• Reformatted 16 files (13 source files, 1 notebook, 2 test files)
• Primary change: removed extraneous blank lines to comply with black 26.1.0 formatting rules

All linting checks now pass (black, flake8, mypy).

Contributor checklist:

• I have read and understood CONTRIBUTING.md
• Confirmed an issue exists for the PR
• Confirmed PR is rebased onto the latest base
• Confirmed failure before change and success after change
• Any generic new functionality is replicated across cloud providers if necessary
• Tested manually against live server backend for at least one provider
• Added tests for any new functionality
• Linting passes locally
• Tests pass locally
• Updated HISTORY.md with the issue that is addressed and the PR you are submitting. If the top section is not `## UNRELEASED``, then you need to add a new section to the top of the document for your change.

Original prompt

reformat with the latest version of black so linting passes
