📝 Walkthrough

Walkthrough

This PR extracts project-switch URL construction logic from ListOfProjects into a reusable buildProjectSwitchHref utility. The utility preserves the top-level page section while stripping entity-scoped routes and optionally carries forward the settings-page tab parameter. The refactored component now delegates URL building to this helper instead of inline logic.

Changes

Project-switch routing refactor

Layer / File(s)	Summary
Core URL routing utility web/oss/src/components/Sidebar/components/assets/projectSwitchHref.ts	New exported buildProjectSwitchHref function and BuildProjectSwitchHrefParams interface derive destination URLs by extracting the top-level route from the current path, defaulting to "apps", and appending tab query params only for settings pages.
URL routing utility tests web/oss/src/components/Sidebar/components/assets/projectSwitchHref.test.ts	Vitest regression suite validates path rewrites across entity types (evaluations, testsets, apps/playground sub-routes), query-param stripping for non-settings pages, and settings-page tab parameter preservation with override logic.
Component integration web/oss/src/components/Sidebar/components/ListOfProjects.tsx	navigateToProject imports and uses buildProjectSwitchHref instead of inline URL construction, passing workspace/project IDs, current path, and tab parameters.
