Add calendar integration to create study review reminders #15
Description
Is your feature request related to a problem? Please describe.
Users can easily miss the right time to review their lessons because reminders are not automatically added to their personal calendars.
Describe the solution you'd like
Allow the platform to create a calendar event in the user's calendar (Google, Outlook, Apple, iOS, Android) for the next review session, based on spaced repetition, with a message like:
Time to review your English lessons with spaced repetition!

Describe alternatives you've considered
- Manual calendar reminders
- Email or push notifications only
- In-app reminders without calendar integration
Additional context
An initial version could generate an .ics file that users can import into any calendar, with future support for direct calendar integrations.
