Add Group Setting to Restrict Thesis Applications Visibility to Responsible Advisors/Supervisors

[vikikab]

Description

Currently, when a student applies for a thesis:

• The application email is sent to all group members of the respective group.
• The application is visible to all group members in the system.

This behavior does not allow for restricted visibility when multiple advisors/supervisors exist within the same group.

In groups with multiple advisors and supervisors, thesis applications should only be accessible to the advisors/supervisors responsible for the specific thesis. The current implementation exposes applications to all group members, which is not always desired.

Proposed Solution

Introduce a Group Setting option that allows configuration of application visibility.

When enabled

• Application emails are sent only to the responsible advisors/supervisors of the thesis.
• The application is only visible in the system to those responsible advisors/supervisors.
• Other group members cannot see or access the application.

When disabled (default behavior)

• Applications remain visible to all group members.
• Emails are sent to all group members.

Acceptance Criteria

• New group setting is available in Group Settings.
• Setting can be toggled on/off.
• Email distribution respects the setting.
• UI visibility respects the setting.
• Proper permission checks implemented at backend level.
• Existing behavior remains unchanged when setting is disabled.
• Tests added for both visibility modes.
