Tasks API updates - syncScope, originalWordsCount, and model fixes

Several updates landed on the Tasks API models that typed client libraries should pick up:

**New response fields:**

- `originalWordsCount` (integer) on the Task model — the number of words when the task was created, preserved when source strings are later removed (`wordsCount` reflects the current count). Both Crowdin and Crowdin Enterprise.
- `syncScope` (nullable object: `syncedWords`, `pendingWords`, `skippedWords` — all integers) on the Enterprise task models (project tasks, organization task list, user tasks). It is `null` when the task is fully synced, not shared, or the counterpart is unavailable — **Crowdin Enterprise only**.

**Type fixes:**

- Task `creatorId` corrected from string to **integer**.
- Enterprise Add Task forms: `status` corrected from integer to **string** enum (`todo`, `in_progress`).

**Edit Project Task (Enterprise):** the inter-organizational task patch `path` enum gains `/generateCostEstimate`, `/generateTranslationCost`, and `/reportSettingsTemplateId`.

Affected endpoints: **List/Add/Get/Edit Project Task** (`api.projects.tasks.getMany`/`post`/`get`/`patch`), **List Tasks** (Enterprise organization level, `api.tasks.getMany`), **List User Tasks** (`api.users.tasks.getMany` on crowdin.com).

- [Edit Task](https://support.crowdin.com/developer/api/v2/#operation/api.projects.tasks.patch)
- Crowdin Enterprise: [List Tasks](https://support.crowdin.com/developer/enterprise/api/v2/#operation/api.tasks.getMany), [Edit Task](https://support.crowdin.com/developer/enterprise/api/v2/#operation/api.projects.tasks.patch)

Start by inspecting the typed models used by the listed project, organization, and user task endpoints, using the linked API references to verify the response fields and enum values. Done means the affected Crowdin and Enterprise models expose the new fields, corrected types, and patch paths with the documented nullability and Enterprise-only scope.
