CR38 — verify/complete 3h-food / 24h-rest claim re-appearance

Client CR38 (Ayudarg-todo): una necesidad TOMADA que no se cumple debe volver a aparecer para tomar — 3h para la comida, 24h para el resto de las necesidades. Recent AYUD-78 work built claim-expiry (comida 3h / resto 24h), isClaimable exposure on need queries, and a daily cron sweep. TASK: verify end-to-end that this actually works in prod — claim a need → after the window it re-surfaces as claimable (isClaimable flips, button reappears) even before the cron runs (server-side guard), and the cron sweeps stale claims. Confirm food=3h vs rest=24h is correctly categorized (which lookupValues category/goods drives 'comida'?). If fully working → mark done. If gap (e.g. category mapping wrong, UI not re-showing, cron cadence blocked by Hobby-plan daily limit) → finish it. Coder assesses code path; db confirms the expiry/category data + cron. Auditor deploy-verifies any push.
