📋 Summary

This PR introduces comprehensive timezone support for the user profile and Leitner box scheduling system. It adds a new TimezonePicker component that replaces the native select dropdown on the profile settings page, enabling users to set their timezone more intuitively. The Leitner box review scheduling and display have been enhanced to support automatic resynchronization when a user's timezone is updated. Additional clarifications and translations related to timezone handling in Leitner settings have also been included. Testing and fixes for timezone support in schedule catch-up logic were implemented to ensure accuracy.
