Convert ExecutionEnvironment route tree to react-router v6 Routes

[blaipr]

SUMMARY

Continues the react-router v5 → v6 route-tree migration. Converts the ExecutionEnvironment screen's route trees from the v5 <Switch>/<Route>/<Redirect> API to v6 <Routes>/<Route> via react-router-dom-v5-compat, following the pattern used for the Application, CredentialType, NotificationTemplate and Team route trees.

UI (no behavior change — same URLs, same panels):

• ExecutionEnvironments.js (list router): <Switch> → <Routes>; child routes use the element prop; the detail route is /execution_environments/:id/* so the nested <ExecutionEnvironment> tree can match the rest of the path.
• ExecutionEnvironment.js (detail router): <Switch> → <Routes> with relative child paths (edit, details, templates); the exact <Redirect> becomes an index route that <Navigate replace>s to details.
• Tests: the list test is converted to RTL and a new detail test is added, both using renderWithContexts to assert real v6 route resolution (which panel renders per URL, index redirect, 404 error).

ISSUE TYPE

• Bug, Docs Fix or other nominal change

COMPONENT NAME

• UI

ADDITIONAL INFORMATION

• Part of the incremental react-router v6 migration; each screen's route tree is independent and converted on its own branch off main.
• Tests: 8 route-resolution tests across the two suites; full screens/ExecutionEnvironment directory passes (10 suites / 51 tests).
• npm --prefix awx/ui run lint clean on the changed source.

Pull request overview

Continues the incremental react-router v5 → v6 migration by converting the ExecutionEnvironment screen’s list and detail route trees to v6-style <Routes>/<Route> via react-router-dom-v5-compat, while updating/adding RTL tests to validate route resolution and redirects.

Changes:

• Migrated ExecutionEnvironments (list) route tree from <Switch> to <Routes>, including updating the detail route to /execution_environments/:id/* for nested matching.
• Migrated ExecutionEnvironment (detail) route tree from <Switch>/<Redirect> to <Routes> with relative child paths and an index redirect via <Navigate replace>.
• Converted/added React Testing Library tests to assert real v6 route resolution, including index redirect and 404 behavior.

Thanks for the review. Fixed the doubled /* /* in the nested-route comment in 768410eae6.
