test: fix stale requireSession mocks after auth-widening pass (v0.30.1)

Four route test files still mocked requireSession after their routes
were converted to requireSessionOrApiKey in an earlier commit this
session — every test in them was failing at the auth call before
reaching the logic under test. Also adds the missing inArray export
to one file's @epicure/db mock, uncovered once its auth mock was
fixed and the test could actually run further.

No production code changed; two unrelated pre-existing failures
(lib/__tests__/tiers.test.ts, lib/__tests__/webhooks.test.ts) remain
and are confirmed present on main before this session's changes.
