Student count mismatch between real number of records and Roll-Up Summary value

**Description**
> When loading the student list, the network tab initially showed only 4 students, while the UI displayed 82 students. After marking students present and refreshing the screen, the API correctly returned 82 students (as confirmed in the second image’s network tab).

**Root Cause**
We currently use a Roll-Up Summary Field in Salesforce to calculate the number of records. According to Salesforce documentation, updates can take up to 30 minutes, which likely explains the discrepancy.

**Next Steps / Proposal**
• Investigate alternatives to Roll-Up Summary Fields for more accurate, real-time counts.
• Consider running a SOQL query on every call to ensure the student count is always up to date.
