Use /admin/settings route and update RequestCard tests

Change the settings navigation in BookDatePage to push to /admin/settings and update the corresponding test to expect the new route. Simplify RequestCard tests by removing manual/interactive search mocks and modal, remove interactiveSearch permission from the mocked AuthContext, and adjust tests to only assert cancel behavior; add a new test ensuring Manual/Interactive Search buttons are not rendered. Misc: clean up related mock resets and removed a failing manual-search failure test.
