Ingen content for 503-feil i Swagger

[esseb]

Description of the bug

503 errors i https://docs.altinn.studio/swagger/altinn-broker-v1.json mangler content. Er dette riktig eller burde de også ha #/components/schemas/ProblemDetails som andre feil har:

"content": {
  "application/json": {
    "schema": {
      "$ref": "#/components/schemas/ProblemDetails"
    }
  }
}

Dette gjelder:

• POST broker/api/v1/filetransfer
• POST /broker/api/v1/filetransfer/{fileTransferId}/upload
• POST /broker/api/v1/filetransfer/upload.

Steps To Reproduce

Ikke relevant.

A summary of the changes CodeRabbit can apply:

• Update 35 error response attributes across src/Altinn.Broker.API/Controllers/FileTransferController.cs (26 responses), ResourceController.cs (5), and ServiceOwnerController.cs (2) to change ProducesResponseType(StatusCodes.StatusXXX) to ProducesResponseType(typeof(ProblemDetails), StatusCodes.StatusXXX) so Swagger/OpenAPI responses include a JSON ProblemDetails content schema for all error responses.

• Update API response annotations: modify FileTransferController, ResourceController, and ServiceOwnerController to replace untyped [ProducesResponseType(StatusCodes.Status...)] entries with typed [ProducesResponseType(typeof(ProblemDetails), StatusCodes.Status...)] (preserving existing typed 200/200OK response types and routes) across the listed controller action attributes.
