2.4.2 updates to built in template

Changed

• 🔄 Unified Alert Display - Merged ongoing and expected alerts back into single attribute
  • All alerts now display together in formatted_content (both current and future)
  • Alerts sorted by start date (latest/furthest in future first), then by severity
  • Simplified display - no need for separate cards for ongoing vs. expected

Breaking Changes

• Removed Attributes - The following attributes have been removed:
  • formatted_content_expected - merged into formatted_content
  • ongoing_alerts - count removed (use active_alerts for total)
  • expected_alerts - count removed (use active_alerts for total)
• Migration: If you were displaying formatted_content_expected in a separate card, update your card to use formatted_content which now includes all alerts
  • If you need separate ongoing/expected displays, see the documentation section on creating custom Jinja2 templates for markdown cards
