Multiple reminders for appointments

Sometimes it would be helpful to have multiple reminders e.g. 15 minutes before and 1 day before.

Calendar events can now carry multiple reminders — e.g. 15 minutes before and 1 day before. The event dialog manages them as an add/remove list (up to 5 per event), and each reminder is delivered independently via in-app badges, opt-in Web Push, and any configured notification channels (Gotify/ntfy).

Thanks for the idea!
