Fix violations of static analysis for pytests

[jakub-vavra-cz]

Enable static analysis on pushes and pull requests. Fix some isort and typing issues.

Summary by Sourcery

Enable static analysis for the pytest test suite and align test and configuration code with the new linting and typing requirements.

Enhancements:

• Reformat pytest sudo tests and adjust assertions and string concatenations to comply with ruff formatting and style rules.
• Update sudo alias usage in tests to use alias names and string members for better compatibility with static typing and linting.
• Reorder imports in tests to satisfy isort-style ordering enforced by ruff.

Build:

• Configure ruff (lint and format) and mypy in pyproject.toml, including line length, target version, and enabled rule sets, and remove redundant flake8 configuration.

CI:

• Add a static code analysis job to the main CI workflow to run ruff (lint and format) and mypy on the pytest project, including virtualenv setup and dependencies.
• Remove the separate static-code-analysis workflow in favor of the new integrated CI job.

Reviewer's Guide

Adds a static code analysis job to the main CI workflow, configures Ruff and mypy in pyproject, and adjusts pytest sudo/security tests (including sudo alias usage and assertion formatting) to satisfy Ruff/isort/typing checks while removing the old standalone static-code-analysis workflow.

File-Level Changes

Change	Details	Files
Enable static code analysis (Ruff + mypy) as part of the main CI pipeline.	Add a static-code-analysis job to run on ubuntu-latest with Python 3.x Set up a virtualenv under ./pytest and install test requirements plus ruff and mypy Run ruff check, ruff format --check, and mypy on pytest tests, all guarded with if: always() to report even on failures	.github/workflows/ci.yml
Configure Ruff and update linting configuration for the pytest project.	Add Ruff configuration including line length, target Python version, and excluded paths Configure Ruff lint rules to include pycodestyle, pyflakes, and isort, and enforce from future import annotations as a required import Configure Ruff formatter preferences (quotes and indentation) Remove legacy flake8 configuration now superseded by Ruff	pytest/pyproject.toml
Align sudo alias usage in pytest tests with string-based identifiers expected by static analysis and underlying sudo tooling.	Change sudo user alias definitions to pass user/group names (e.g. u.name, g.name) instead of user/group objects into client.sudoalias.add Change sudo rules to reference user/command/host aliases by their alias names (e.g. 'SUDO_USERS', 'LSHELP', 'TRUSTED', 'RUN_AS') instead of passing alias objects	pytest/tests/test_basic.py
Refactor pytest assertions and imports to satisfy Ruff/isort and style rules without changing test behavior.	Reorder imports so pytest and stdlib imports precede local imports and enforce future import position Collapse multi-line assert calls into single logical lines with the message wrapped in parentheses to conform to line-length and formatting rules Apply similar assertion formatting updates in miscellaneous sudo-related tests	pytest/tests/test_basic.py pytest/tests/test_misc_issues.py pytest/tests/test_sudo.py pytest/tests/test_security.py
Simplify mailer sudoers string construction in the security test to avoid multi-line string concatenation issues flagged by static analysis.	Replace a parenthesized multi-line string concatenation with a single f-string containing embedded newlines for the sudoers configuration	pytest/tests/test_security.py
Remove the old static-code-analysis workflow now that static analysis runs as part of the main CI workflow.	Delete the standalone .github/workflows/static-code-analysis.yml workflow file	.github/workflows/static-code-analysis.yml
