feat(events): add icalUid to ListEventQueryParams

[openclaw-sre-agent]

Summary

Add the missing icalUid optional field to ListEventQueryParams so customers can filter events by iCalendar UID without casting queryParams to any.

Root Cause

ListEventQueryParams has 17 typed fields but icalUid / ical_uid was never included, even though the v3 API accepts it on GET /v3/grants/{identifier}/events and the Event response model already has icalUid at line 84. A related PR that added the attendees filter missed this field.

Fix

Single-field addition: icalUid?: string on the query params interface. The SDK's apiClient already converts camelCase keys to snake_case in query parameters, so icalUid is sent as ical_uid on the wire — no serialization changes needed.

Before / After

// Before — requires unsafe cast
await nylas.events.list({
  identifier: grantId,
  queryParams: {
    calendar_id: calId,
    ical_uid: uid,
  } as any,
});

// After — fully typed
await nylas.events.list({
  identifier: grantId,
  queryParams: {
    calendarId: calId,
    icalUid: uid,
  },
});

Validation

• tsc --noEmit passes cleanly
• No other files affected

Fixes CUST-5473
