fix(ui): stub useIsOrgAdmin in UsageTab tests so useCan needs no QueryClient

[ryan-crabbe-berri]

TLDR

Problem this solves:

• ui-unit-tests is red on litellm_internal_staging itself
• All 18 UsageTab tests fail with "No QueryClient set"
• Every open PR inherits the red check from the base

How it solves it:

• Stub useIsOrgAdmin, the leg of useCan that needs react-query
• Role gating still runs through the real hasCapability

Screenshots / Proof of Fix

Commit 255d651 added useCan to UsageTab. useCan calls useIsOrgAdmin, which calls useOrganizations, a react-query hook, and the test renders UsageTab without a QueryClientProvider, so the whole suite throws before asserting anything

On origin/litellm_internal_staging (cbf85a0):

npx vitest run "src/app/(dashboard)/cost-optimization/_components/UsageTab.test.tsx"
# -> Tests  18 failed (18), every case: "No QueryClient set, use QueryClientProvider to set one"

With this fix:

npx vitest run "src/app/(dashboard)/cost-optimization/_components/UsageTab.test.tsx"
# -> Tests  18 passed (18)

The stub returns false, the value a non org admin gets, so the role-varied cases the gating commit added (Admin vs Internal User on the spend-by-tool card) still exercise the real hasCapability path

Type

✅ Test

Caveats (if any)

Final Attestation

• The tests check the right things, including the edge cases, and regressions in the respective real-world customer use-cases are not possible after this PR

Greptile Summary

This PR restores the UsageTab unit-test suite by stubbing the React Query-dependent organization-admin hook while leaving the relevant role-capability checks active.

• Adds a test-local useIsOrgAdmin mock returning the non-organization-admin state.
• Avoids requiring a QueryClientProvider in the 18 existing UsageTab tests.
• Preserves the real hasCapability path used by the spend-by-tool role-gating cases.

Confidence Score: 5/5

The PR appears safe to merge because the new test stub does not alter the capability outcomes covered by UsageTab.

The only gated capability in these tests is determined by the user-role branch of hasCapability, so forcing the unrelated organization-admin hook to false removes the missing-QueryClient failure while preserving the tested Admin, Internal User, Internal Viewer, and Org Admin behavior.
