Pull request overview

This PR consolidates all event classes from sub-packages (e.g., callout, callback, face, fingerprint, subject, samples, upsync, downsync) into the single parent package com.simprints.infra.events.event.domain.models. Additionally, it refactors Event and EventPayload from abstract to sealed classes, improving type safety.

Changes:

• Moved all event classes from sub-packages into a single package, eliminating hierarchical package organization
• Refactored Event and EventPayload from abstract to sealed classes
• Moved BiometricDataSource from callout sub-package to root models package

• Changing getTokenizableFields() from abstract to open with a default empty map implementation may break existing implementations that override this method. While sealed classes ensure all implementations are known at compile-time, this changes the contract. Consider verifying all subclasses still provide meaningful implementations where needed, as some may now silently fall back to the empty map default.

• The fully qualified references BiometricReferenceType.Companion.FACE_REFERENCE_KEY are more verbose than necessary. Since the original code used direct imports, consider maintaining consistency by importing these constants directly instead of using fully qualified names.
