Room Header Buttons Ordering

Currently, Rocket.Chat Room Header actions follow rigid layout rules, often hiding critical tools in overflow menus and reducing workspace flexibility . This project proposes a configurable layout engine that allows administrators to define action ordering and pinning (featured) via a workspace-level JSON setting. Key deliverables include a dynamic administration UI built with Fuselage, a per-user Feature Preview for progressive rollout, and a comprehensive test suite using Jest, Playwright, and axe to ensure 100% scenario validation and zero accessibility violations .
