- Introduce DisplayCoordinator polling /api/display/monitors once per cycle and fan out to all per-display entities via CoordinatorEntity. Removes ~9x redundant requests per polling cycle that came from each binary_sensor/number/select/sensor/switch entity calling get_display_monitors() in its own async_update. - Optimistic write-through via coordinator.apply_optimistic(...) keeps sibling entities in sync after slider/select writes without an extra network round-trip. - Make CONF_TOKEN optional. The media server already supports running without auth (auth_enabled() returns False when api_tokens is empty), so the integration omits the Authorization header and ?token= query from REST/WS/album-art URLs when no token is configured. Server-side auth-enabled rejections still surface as invalid_auth in the UI. - Bump manifest version to 0.3.2. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
