Upgrade ruff to 0.16.5 and address new rules

[oschwald]

Dependabot's ruff 0.16 bump fails CI because 0.16 stabilized new rules and started formatting Python fences in Markdown. This PR bumps ruff and addresses the failures.

• Bump ruff to 0.16.5 in uv.lock. The dependabot PR closes when this merges.
• Ignore CPY001 (missing-copyright-notice). We do not want a copyright header on every file.
• Suppress PLR0917 (too-many-positional-arguments) on the web-service client constructors and the minFraud models, where making the arguments keyword-only would break callers that pass them positionally. The existing PLR0913 suppressions do not cover the new rule.
• Reformat the Python code blocks in Markdown. ruff 0.16 formats these by default.

Each change is its own commit.

Ruff grows quiet, rules align
One date line curls up neat
