fix: parallelize WA sync and surface scheduler errors in historial

- whatsapp_sync: send patients concurrently (asyncio.gather + semaphore=10) instead of sequentially — eliminates long waits with many patients
- envios_erp: auto-refresh historial every 60s when scheduler tab is active
- main: wrap scheduler job to catch exceptions and log them to sync_wa_log so failures are visible in historial
