🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep the assignee identifiable in cross-staff feeds.

When an authorized request selects another staff_id, calendarName(auth) names the viewer, but the event summary no longer names turn.getStaff(). The description and category do not supply the assignee either. A subscriber cannot tell whose duty a returned event represents. Preserve the staff name for turns assigned to someone other than the viewer, or restrict this feed to the viewer’s turns. (raw.githubusercontent.com)

Update the event summary generation in DutyRosterTurnIcsWriter so turns assigned
to someone other than the authenticated viewer still identify the assignee by
name. Preserve the existing summary for the viewer’s own turns and use the staff
identity available from turn.getStaff().

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Require HTTPS for the public ICS base URL.

If an operator configures an http:// base URL, Line 4330 places the duty-roster JWT in plaintext calendar requests. The configured JWT has no expiry by default. Reject non-HTTPS public base URLs before showing or generating a subscription link. Based on learnings, URL query parameters can expose access tokens; HTTP adds plaintext transmission to that risk.
