Fixes https://github.com/payloadcms/payload/issues/11473 Previously, when `disablePayloadAccessControl: true` was defined, client uploads were working improperly. The reason is that `addDataAndFileToRequest` expects `staticHandler` to be defined and we don't add in case if `disablePayloadAccessControl: true`. This PR makes it so otherwise and if we have `clientUploads`, it pushes the "proxied" handler that responses only when the file was requested in the context of client upload (from `addDataAndFileToRequest`)
