test(auth): freeze prefetch cache clock so the org getter cannot miss on a slow runner

[cursor]

TLDR

Problem this solves:

• Postgres Tests has been failing on every push to litellm_internal_staging since perf(auth): read user, team, membership, org, project and spend counters in one MGET, one query and one pipeline #40834
• test_join_binds_the_membership_to_the_requested_team intermittently trips a MagicMock await TypeError

How it solves it:

• Backport the frozen-clock fix that already landed on main in fix(auth): load team membership once per request and skip prisma on an L1 hit #41102 (commit f4e21430c0)
• Injects a frozen clock into InMemoryCache so the 5s org TTL cannot expire mid-test

Screenshots / Proof of Fix

All four push runs of the Postgres Tests workflow on litellm_internal_staging since #40834 landed have failed on the same test:

• https://github.com/BerriAI/litellm/actions/runs/34906640889 (HEAD af6dc1db08)
• https://github.com/BerriAI/litellm/actions/runs/34902129705 (HEAD 3f32a19d55)
• https://github.com/BerriAI/litellm/actions/runs/34888630105 (HEAD 1f8bae7eab)
• https://github.com/BerriAI/litellm/actions/runs/34888579292 (HEAD 8d5c165547)

All four fail with the identical:

FAILED tests/proxy_behavior/auth/test_auth_object_prefetch.py::test_join_binds_the_membership_to_the_requested_team - TypeError: object MagicMock can't be used in 'await' expression

Root cause (quoted from the main fix commit f4e21430c0): the org cache entries written by prefetch_auth_objects carry the 5s DEFAULT_IN_MEMORY_TTL. The first @log_db_metrics getter lazily imports litellm.proxy.proxy_server, which on a cold CI runner can take longer than 5s, so the org entry expires before get_org_object reads it and the getter falls through to the MagicMock dead_db, whose db.litellm_organizationtable.find_unique(...) returns a non-awaitable MagicMock.

Main has been green on the same workflow since the fix landed (e.g. run https://github.com/BerriAI/litellm/actions/runs/35010237987, push main at 2026-09-15 18:53Z, Postgres Tests succeeded).

This PR is a mechanical backport of the exact test-only diff on main, verified with git diff origin/main -- tests/proxy_behavior/auth/test_auth_object_prefetch.py returning empty after the change.

Caveats

Low

• Test-only change; no production code path is touched.

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
