🐛 fix(duplicate-event): fix event duplication - web

[victor-enogwe]

What does this PR do?

Web fix

The duplicate functionality was completely broken for both calendar and someday events. When users attempted to duplicate an event via right-click context menu or the Meta+D keyboard shortcut, no new event was created and the UI did not update. This regression was introduced in commit 2de11df during the recent refactoring of draft actions.

Root Cause

The duplicateEvent function in useDraftActions.ts was incorrectly passing the original event's _id to the submit function:

const duplicateEvent = useCallback(() => {
  const draft = MapEvent.removeProviderData({
    ...reduxDraft,
  }) as Schema_GridEvent;

  submit(draft); // ❌ This includes the original _id
  discard();
}, [reduxDraft, submit, discard]);

When an event has an existing _id, the submit function treats it as an edit operation rather than a create operation, causing the duplicate to overwrite the original event instead of creating a new one.

Pull Request Overview

This PR fixes a critical bug in the event duplication functionality for the web application. The issue was that when users attempted to duplicate events through right-click context menu or Meta+D shortcut, no new event was created because the duplicate function was passing the original event's _id, causing the system to treat it as an edit operation instead of a create operation.

• Fixes the duplicateEvent function to properly generate optimistic IDs for new events
• Updates type definitions to use more specific Schema_WebEvent types instead of generic Schema_Event
• Adds proper type safety and validation improvements across event handling utilities
