feat(ai): add support for AI Translate Strings endpoint

[AGSAVALIYA]

Description

Adds support for the new AI Translate Strings endpoint introduced in the Crowdin API.

Changes

• Added aiUserTranslateStrings(userId, request) method to the Ai class — issues POST /users/{userId}/ai/translate/strings
• Added AiModel.AiTranslateStringsRequest type (request body: projectId, languageId, optional stringIds[])
• Added AiModel.AiTranslateStringsAttribute type (response attribute)
• Added corresponding nock mock and test case in tests/ai/api.test.ts

References

• API docs: https://support.crowdin.com/developer/api/v2/#tag/AI/operation/api.users.ai.translate.strings.post

Resolves #617

---

Note

Low Risk
Low risk: adds a new POST /users/{userId}/ai/translate/strings client wrapper and corresponding types/tests without changing existing request flows.

Overview
Adds support for the Crowdin AI Translate Strings user endpoint by introducing aiUserTranslateStrings() on the Ai client, issuing POST /users/{userId}/ai/translate/strings.

Extends AiModel with request/response types (AiTranslateStringsRequest, AiTranslateStringsAttribute) and adds a nock mock + test coverage to validate the new call returns a job identifier.
