fix(ai): correct AI Translate Strings implementation for Crowdin and Enterprise

[Copilot]

PR #625 implemented the AI Translate Strings endpoint with the wrong URL, request schema, response shape, and was missing the Crowdin Enterprise variant entirely.

Corrections to existing translateAiUserStrings

• URL: /users/{userId}/ai/translate/strings → /users/{userId}/ai/translate
• Return type: Dropped Status<> async job wrapper — response is synchronous
• AiTranslateStringsRequest: Replaced { projectId, languageId, stringIds? } with the correct schema:
  • Required: strings: string[], targetLanguageId: string
  • Optional: sourceLanguageId, tmIds, glossaryIds, aiPromptId, aiProviderId, aiModelId, instructions, attachmentIds
• AiTranslateStringsAttribute → renamed to AiTranslateStringsResponse with fields: sourceLanguageId, targetLanguageId, translations: string[]

New: Crowdin Enterprise support

Added translateAiOrganizationStrings(request) using POST /ai/translate (no userId in path). Reuses the same request/response types — the schemas are identical.

// Crowdin
const result = await crowdin.ai.translateAiUserStrings(userId, {
    strings: ['Hello world'],
    targetLanguageId: 'uk',
    sourceLanguageId: 'en',
});
console.log(result.data.translations); // ['Привіт світ']

// Crowdin Enterprise
const result = await crowdin.ai.translateAiOrganizationStrings({
    strings: ['Hello world'],
    targetLanguageId: 'uk',
});
console.log(result.data.translations); // ['Привіт світ']
