Fix Yandex Station credential borrowing and stream playback

[trudenboy]

What does this implement/fix?

Synchronizes the Yandex Station provider from v1.5.6 to v1.5.6 and fixes two
regressions affecting current Music Assistant and Yandex Station installations.

Authentication borrowing

• Reads linked Yandex Music credentials from guided setup data, while retaining
  the legacy provider-config fallback.
• Waits briefly when the linked Yandex Music provider has not finished loading,
  avoiding a startup-order race that previously left the Station provider
  unavailable.
• Updates the shared authentication dependency to
  ya-passport-auth[ma]==1.8.0.

Stream playback on current Station firmware

• Detects the advertised audio_client capability and sends audio_play with
  track/HLS metadata on current firmware.
• Retains radio_play as a fallback for older firmware.
• Uses the matching pause/stop behavior for each playback mode and consumes
  progress reported by audio_play.
• Attributes Glagol state transitions to the requested track, so stale state
  from the previous source cannot turn a normal track handoff into a reported
  physical pause.
• Uses the same firmware-aware stream command for announcements and preserves
  compatibility with cores that do not expose the announcement-duration
  resolver.

The PR also includes the corresponding authentication, setup-flow,
announcement, protobuf, player-state, and project-consistency tests, plus a
small return-type normalization for generated QR data URIs.

music_assistant/providers/yandex_station/borrow.py:39

• [CRITICAL] This early return gives legacy config precedence whenever either old token remains, so guided-flow setup data—including rotated or deliberately cleared credentials—is ignored and borrowing can authenticate with stale credentials; retain super().read_tokens() for validation/fallback but prefer owner.get_setup_value() when available.

        music_token, x_token = super().read_tokens()
        if music_token is not None or x_token is not None:
            return music_token, x_token

music_assistant/providers/yandex_station/provider.py:474

• [PROBLEM] resolve_music_token() also raises ResourceTemporarilyUnavailable for Passport network/rate-limit failures, so this loop can retry an external call 40 times at 250 ms instead of only waiting for provider load; poll the non-networked read_tokens() readiness first, then resolve once so the normal retry/backoff handles Passport outages.

            except ResourceTemporarilyUnavailable:
                if attempt == _BORROW_SOURCE_LOAD_ATTEMPTS - 1:
                    raise
                await asyncio.sleep(_BORROW_SOURCE_LOAD_DELAY)

music_assistant/providers/yandex_station/player.py:1212

• [PROBLEM] This applies progress even when external_media_matches is False, so the stale old-track update explicitly handled above is exposed as the newly requested track's elapsed position; ignore progress from known-mismatched player state.

            if self._external_audio_client:
                self._attr_elapsed_time = progress
                self._attr_elapsed_time_last_updated = time.time()
