[Abi107717]

Checklist

General

• I tested all changes and their related features with all corresponding user types.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) and too complex database calls.
• I documented the Java code using JavaDoc style.

Motivation and Context

When a professor manually schedules an interview for an applicant, only the applicant receives a confirmation email with the ICS file. The professor currently receives no notification or calendar invite, unlike the self-scheduling flow where both parties are notified.

Description

• Added a new email type INTERVIEW_ASSIGNED_PROFESSOR specifically for manual assignment.
• Implemented InterviewService.sendInterviewInvitationEmail to send a confirmation email with an ICS attachment to the supervising professor.
• Created corresponding email templates for English and German.
• Updated tests to verify that both applicant and professor receive their respective confirmation emails.
