add Yandex Disk provider

[trudenboy]

What does this implement/fix?

Adds a new Yandex Disk music provider (filesystem_yandex_disk) that streams music, audiobooks and podcasts stored on a user's Yandex Disk.

Source: trudenboy/ma-provider-yandex-disk · tag v0.1.0 · documentation

Highlights

• Browse and stream audio files from a configured Yandex Disk folder, with library sync (tracks / albums / artists / playlists) and seek support.
• Read-only OAuth authentication (cloud_api:disk.read scope) with automatic token refresh. Uses the user's own Yandex OAuth application via Yandex's confirmation-code flow — the user pastes the code Yandex shows, no redirect URI to register.
• Architecture mirrors the existing Google Drive provider; the Yandex Disk REST API is accessed through the yadisk library (yadisk==3.4.1).
• Supports multiple instances (e.g. different accounts or folders).
• Test suite included under tests/providers/filesystem_yandex_disk/ (API client, auth, config flow, provider, integration) with JSON fixtures.

Tests are failing and the checklist item for documentation is not there but that needs to be done.

Pull request overview

This PR adds a new cloud filesystem music provider (filesystem_yandex_disk) that integrates Yandex Disk into Music Assistant via the existing CloudFileSystemProvider abstraction (browse/sync/stream via MA proxy), including OAuth-based authentication and a yadisk-backed async API client.

Changes:

• Added filesystem_yandex_disk provider implementation (provider wiring, OAuth helper, yadisk API wrapper, manifest/icons/version, strings).
• Added a dedicated test suite under tests/providers/filesystem_yandex_disk/ with fixtures and integration coverage of CloudFileSystemProvider._scandir.
• Added yadisk==3.4.1 to requirements_all.txt and added provider translation strings.
