PR Summary

• Implementation of Settings Retrieval
  The PR includes updated code which allows us to fetch our application's settings and store them for further use.

• Setting Audit Warning Duration
  From these settings, we extract and store the "audit_warning_days" value specifically. This represents a certain time period in days that we're particularly interested in.

• Calculation of Future Date
  We take the current date and add the "audit_warning_days" value to it. This helps us predict a future date, referred to as "interval_date" in the code. This assists in determining when our next audit warning should be triggered.
