Pull request overview

This pull request implements an evidence notification digest feature that allows users to receive scheduled email summaries of their evidence compliance status. The digest highlights evidence that requires attention (not-satisfied and expired items) and includes a scheduler infrastructure to support recurring jobs.

Changes:

• Adds a cron-based scheduler service with support for daily, weekly, and monthly jobs
• Implements a digest service that aggregates evidence statistics and sends HTML/text email digests to subscribed users
• Introduces new API endpoints for managing digest subscriptions and triggering/previewing digests manually
• Adds auto-expiration logic for evidence based on configurable default expiry months
• Updates the User model with a DigestSubscribed field to track subscription preferences
