Convert NotificationTemplate route tree to react-router v6 Routes

[blaipr]

SUMMARY

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

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

• NotificationTemplates.js (list router): <Switch> → <Routes>; child routes use the element prop; the detail route is /notification_templates/:id/* so the nested <NotificationTemplate> tree can match the rest of the path; the unused useRouteMatch match.url is replaced by explicit paths.
• NotificationTemplate.js (detail router): <Switch> → <Routes> with relative child paths (edit, details); the exact <Redirect> becomes an index route that <Navigate replace>s to details; the Details tab link is built from the route id instead of match.url.
• 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: 7 route-resolution tests across the two suites; full screens/NotificationTemplate directory passes (6 suites / 31 tests).
• npm --prefix awx/ui run lint clean on the changed source.

Pull request overview

Migrates the NotificationTemplate screen’s routing from react-router v5 (Switch/Redirect) to v6-style route resolution (Routes/Navigate) via react-router-dom-v5-compat, and updates tests to assert v6 route matching behavior.

Changes:

• Converted the NotificationTemplates (list) and NotificationTemplate (detail) route trees to v6 <Routes> patterns, including nested :id/* matching and an index redirect to details.
• Updated NotificationTemplate list URL construction to use explicit /notification_templates/... paths instead of match.url.
• Converted/added RTL route-resolution tests for list, add, detail, edit, index redirect, and 404 behavior.

Thanks for the review. Addressed in f417913506 and c20c3e6818: fixed the doubled /* /* comment and dropped the unused API mock; and reworked the load so the bare /:id no longer fetches before redirecting. The index <Navigate> now renders unconditionally and the detail/edit routes show a loading fallback, so the bare URL is skipped and only /details fetches. Real navigation (edit to details) still re-fetches, so saved changes are reflected.
