Automated tests now run with stricter validation enabled, helping catch component setup issues earlier before they reach users. This improves quality assurance across the web interface and related website learning features without changing day-to-day user behavior.

This commit ensures tests are run in debug mode so that props validation is required for tests to pass. This was supposed to be part of https://github.com/odoo/odoo/pull/143209 but was mistakenly removed by a conflict.

The web module's internal HTTP service tests were moved to a newer testing framework. This helps maintain the quality and reliability of web networking behavior without changing what end users see.
