Feat: notification deletion

[miretskyd]

Note

Always show a delete button for each reminder and move the add-reminder button outside the list for consistent access.

• Frontend
  • Calendar (client/src/routes/calendar/+page.svelte)
    • Reminder UI: always render per-item delete button (remove length/last-item conditions).
    • Add-reminder button moved outside the loop to add new reminders consistently.
