fix: update tests for admin-auth-required GET endpoints (PR #6197 reviewer feedback)

[BossChaos]

Summary

Addresses reviewer feedback on PRs #6191 and #6197.

PR #6197 — test_machine_passport.py fixes

All Machine Passport GET endpoints now require admin auth. Tests updated accordingly:

Test	Before	After
test_list_passports_empty	200	401 (unauthenticated)
test_list_passports_rejects_non_integer_limit	400	401 (auth checked before parsing)
test_list_passports_rejects_negative_offset	400	401 (auth checked before parsing)
test_list_passports_clamps_large_limit	unauthenticated	X-Admin-Key: expected-admin-key
test_get_nonexistent_passport	404	401 (auth checked before existence check)
test_update_passport_rejects_owner_claim GET call	unauthenticated	X-Admin-Key: expected-admin-key
test_mutating_subresources_fail_closed GET call	unauthenticated	X-Admin-Key: expected-admin-key

PR #6191 — get_contracts() already fixed

node/beacon_api.py get_contracts() already uses admin-only auth in HEAD. The broken agent-signature fallback (_authenticate_contract_agent(get_db(), [], ...)) was removed. No additional code change needed.

This updates the tests for the new admin-auth gate, but it also removes the original endpoint behavior coverage.

The list pagination tests now only assert that unauthenticated requests return 401 for limit=abc and offset=-1. That no longer proves authenticated admin requests still reject invalid pagination with the documented 400 responses. Similarly, test_get_nonexistent_passport now only covers the unauthenticated 401 path, so the authenticated passport_not_found / 404 behavior is no longer tested. A regression that accepts invalid pagination, ignores the offset validation, or returns the wrong result for a missing passport after valid admin auth would pass this test suite.

Please preserve the original behavior coverage by either adding valid X-Admin-Key headers to the existing validation tests, or splitting them into separate auth-gate tests plus authenticated behavior tests.

Validation:

• Inspected the PR diff for node/tests/test_machine_passport.py.
• Confirmed the changed tests cover unauthenticated 401 paths but remove the authenticated invalid-pagination and missing-passport assertions.

Closing — these tests assert behavior that doesn't exist (and conflicts with policy)

Two problems:

1. The tests fail against main. They now assert 401 (admin required) on GET /api/machine-passport (list + the pagination-validation cases), but list_passports() on main has no admin check — it returns 200. I ran them: 5 failures. The server change these tests assume (fix: require admin auth on all Machine Passport GET endpoints #6197, "require admin auth on all Machine Passport GETs") is still open, not merged.

2. The underlying direction conflicts with policy. Machine passports are hardware-provenance / preservation showcase data (architecture, repair logs, lineage, benchmarks) — conceptually like the public Green Tracker. We keep query GET endpoints public; admin-gating the passport listing is the same pattern we declined on test: restore repo-wide CI baseline expectations #6711.

If there's a real reason a specific passport field is sensitive (e.g. it leaks fingerprint/serial detail that aids anti-VM spoofing), the fix is to redact that field from the public response, not lock the whole listing behind admin. Happy to help with that. Closing this test-only PR since it can't be green without #6197, and #6197 itself needs the policy call first.
