profit c5da680add Fixture: unique-per-run nonce eliminates state-pollution false positive
After the serde fix (PR #2, fix/upsert-outcome-serde) landed on main,
re-running this fixture STILL reported "doc_refs field is empty" —
but with a different root cause than the panic.

Root cause: pre-fix runs panicked on response serialization but had
already added entries to state (panic happened between upsert_entry
returning and the handler's serde_json::json! of the response). So
state.json was polluted with __auditor_test_worker__ entries from
those runs, WITHOUT doc_refs (doc_refs wasn't even wired at the time
those state rows were written).

The fixture's `find(endorsed_names.includes(TEST_WORKER_NAME))` was
picking the oldest polluted entry, not the fresh one.

Compounding: discovered a secondary bug while investigating —
upsert_entry's UPDATE branch only merges endorsed_names. doc_refs,
schema_fingerprint, valid_until on an UPDATE are silently dropped.
Filed as task #12, separate PR to follow.

Fix in this fixture: use a nonce suffix on both TEST_WORKER_NAME and
TEST_OPERATION so every run is guaranteed to hit the ADD path in
upsert_entry, sidestepping the UPDATE bug AND eliminating state
pollution entirely.

shipped_phases: [38, 40, 45.1, 45.2]  (was [38, 40, 45.2])
placeholder:    [45.3]                 (was [45.1, 45.3])

One fewer placeholder — exactly because the serde fix merged on
fix/upsert-outcome-serde and the fixture now cleanly exercises the
path. The loop is:
  fixture finds bug → PR fixes bug → fixture re-run confirms fix →
  one fewer placeholder.
