fix(ci): run the admin disabled-mode DB test in the PostgreSQL lane

[wpfleger96]

api::admin::postgres_tests::disabled_mode_allows_unauthenticated_requests_on_the_admin_host falls through to a DB-backed read route but was not #[ignore]d. The test-unit exclusions meant to skip it still named api::admin::tests::…, which stopped matching when #6730 moved the admin tests into mod postgres_tests. As a result the test ran in the infra-free unit job and only passed after waiting out the sqlx acquire timeout (~150s in hosted CI), while the ignored-only PostgreSQL lane never ran it against a real database.

• The test is now #[ignore = "requires PostgreSQL"], like its DB-backed peers, so the PostgreSQL lane runs it.
• The two dead exclusions are removed, and the api::admin clause is just test(/^api::admin::/). nip98_mode_unrostered_signer_does_not_consume_a_replay_slot was already ignored and runs in the PostgreSQL lane.
• The Justfile comment now states the convention (DB-backed admin tests are ignored; non-ignored ones reject before touching the DB), drops the stale reference to a ci.yml step that no longer exists, and keeps the timeout-trap warning.

Review Summary

Overall Risk: NONE

No concrete security, correctness, or reliability issues found. The test is now excluded from database-free unit execution and is correctly discovered by the PostgreSQL CI profile through its postgres_tests module path and ignored-only configuration.

Notes

• No additional limitations were reported.
