Description

I've added 482 site using python uptime-kuma-api on 483 site app dies, the application shows the list of sites as empty (offering to add a new one), API stops working.

👟 Reproduction steps

1. Add 482 sites via API or manually to monitoring

👀 Expected behavior

Sites will be added as they should, as long as the server hardware can handle the load

😓 Actual Behavior

The application opens for a long time (about 5 minutes), after which the list of sites is displayed as empty, and the API does not respond
