Proposed Changes

This PR makes two small improvements to the timetable and map components:

1. Simplified timetable availability check in Description.tsx: Removed the redundant Object.keys(sessions).length !== 0 condition from the timetableUnavailable check (line 22). This condition was unnecessary because optional chaining handles the caee when all three session arrays (F, S, Y) are empty or undefined. The simplified logic is clearer and achieves the same result.

2. Updated map tile URL to HTTPS in CampusMap.tsx: Changed the OpenStreetMap tile layer URL from HTTP to HTTPS (line 154). While HTTP currently works, using HTTPS is a security best practice and prevents potential mixed content warnings when the application is served over HTTPS.

These changes improve code clarity and follow security best practices without affecting functionality.
