- 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.
