Subject: [PATCH] Add attachDeviceToDeployment method to api.ts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements API method to link WP sensors to a beneficiary's deployment
via the Legacy API set_deployment endpoint. Uses proper authentication
through getLegacyWebViewCredentials() and follows existing API patterns.
