fix(secrev): doc-drift fixture py ruff-clean (root CI runs check + format --check)

The repo-root CI lint runs both 'ruff check .' and 'ruff format --check .' over
all fixtures. Fixed E701 one-liners and ruff-formatted the sample-service .py
files (handlers/*, feature_*.py). Fixture content is irrelevant to doc-drift
(keys on file/dir presence + git staleness).
