Add support for Application Consents API

The Crowdin API introduces **Application Consent Decisions** methods for managing consents granted or denied to applications. Note: these endpoints are available on **crowdin.com only** (not in Crowdin Enterprise).

- **List Application Consents** — `GET /applications/consents` (`api.applications.consents.getMany`). Query: `identifier` (string, optional), `orderBy` (`id`, `createdAt`), `limit`/`offset`.
- **Add Application Consent** — `POST /applications/consents` (`api.applications.consents.post`). Request: `identifier` (string, required), `installedBy` (integer, required), `status` (`granted` or `denied`, required), `scopes` (array of strings, optional). Returns `409` on duplicate.
- **Edit Application Consent** — `PATCH /applications/consents/{consentId}` (`api.applications.consents.patch`). JSON Patch with `op: replace` and paths `/status`, `/scopes`.
- **Delete Application Consent** — `DELETE /applications/consents/{consentId}` (`api.applications.consents.delete`).

The response model includes: `id`, `installedBy` (nullable object with `id`, `username`, `fullName`, `avatarUrl`), `identifier`, `name` (nullable), `status`, `scopes`, `createdAt`, `updatedAt`.

Client libraries should add these methods to their Applications API support.
