Pull request overview

Refactors the Event Definition “Summary” step by extracting its rendering logic into reusable helpers, and makes the summary step part of the shared/common wizard steps so it can be reused consistently across the app (e.g., for Sigma-related flows).

Changes:

• Extracted condition/fields/notifications/event-procedure/remediation rendering into a new useEventDefinitionSummaryRenders.tsx helper module.
• Added a Summary step to useEventDefinitionCommonSteps (with optional summaryComponent override) and removed the ad-hoc summary-step push from EventDefinitionFormContainer.
• Updated EventDefinitionSummary to consume the new reusable render helpers/hooks.
