Add scheduled app update checks and notifications

Introduces a scheduled task that checks for apps not updated within a warning threshold and sends notifications to groups. Adds scheduling utilities, constants for scheduling, and logic to format and send update reports for both Apple and Google apps. Also includes a new NonUpdatedApp record and improvements to the Table class for better formatting.
