What is the current behavior?

@ApiProperty does not accept style or explode options. When using a nested object as a query parameter (e.g. Geolocation inside a QueryDto), there is no way to specify style: 'deepObject' without a @ts-expect-error workaround.

This causes Swagger UI to generate flat query strings like ?latitude=5&longitude=1 instead of ?geolocation[latitude]=5&geolocation[longitude]=1.

Issue Number: #3495

What is the new behavior?

ApiPropertyCommonOptions now includes optional style (typed as ParameterStyle) and explode (typed as boolean) properties. These values are passed through to the OpenAPI ParameterObject at the top level, enabling proper serialization of nested query parameters.

Example usage:

@ApiProperty({
  required: false,
  type: () => GeolocationDto,
  style: 'deepObject',
  explode: true,
})
geolocation?: GeolocationDto;
