fix(sat, payments, admin): multiple production fixes

- sat sweep-stale-jobs: increase initial/custom sync threshold 8h→24h to prevent watchdog killing long historical syncs
- sat-client: fix formatDateForSat same-day rejection by auto-adjusting fechaFin
- sat-sync job: check fiel_contribuyente in addition to fiel_credentials for cron eligibility
- database: extend pool idle cleanup from 5min to 12h to prevent pool closure during long syncs
- webhook controller: auto-extend currentPeriodEnd on recurring MercadoPago payments
- invoicing service: auto-send FacturAPI invoice by email after creation
- admin-clientes: fix no-renovaciones detection to include expired trials and deleted subscriptions
