Reviewer's Guide

This PR fixes a regression in query string parsing within the pages module by simplifying input checks and preserving blank values, expands the lint-staged configuration to include pylint, flake8, and black on both source and test files, removes obsolete skip/xfail decorators addressing a now-resolved Werkzeug transfer-encoding bug across multiple tests, and updates the CHANGELOG with the new fix entry.
