"""Teste PRD 5.19 US-003 + US-008 — worker respecta flag `held`.

US-003: claim_one sare peste randurile `queued AND held=1` (tinute manual).
US-008: expire_held expira randurile tinute mai vechi de `held_retention_days`
        (default 90) -> status 'error', rar_error='TINUT_EXPIRAT', purge_after
        DIRECT la momentul expirarii (NU +30z retentie blocati -> nu 120z total),
        apoi purge_expired le sterge (PII purjat).

TDD: testele se scriu INAINTE de modificarea worker-ului.
