Pull request overview

Adds first-class support for infrared receiver entities to the existing infrared domain, complementing existing emitter/send functionality and enabling signal subscription APIs per the referenced architecture discussion.

Changes:

• Split the prior infrared entity concept into distinct InfraredEmitterEntity and new InfraredReceiverEntity base classes, plus a InfraredReceivedSignal model.
• Add receiver-focused helpers (async_get_receivers, async_subscribe_receiver) alongside filtering updates to existing helper(s).
• Update translations/icons and extend the integration’s test suite to cover receiver enumeration, subscription, and state behavior.

• Make the raised error reflect the actual failure case (missing emitter vs. entity exists but is a receiver) by using an emitter-specific translation key/message (or at least wording like “Infrared emitter entity … not found”). With receiver entities now present in the domain, “Infrared entity … not found” can be misleading when a receiver entity_id is passed.

    if entity is None or not isinstance(entity, InfraredEmitterEntity):
        raise HomeAssistantError(
            translation_domain=DOMAIN,
            translation_key="entity_not_found",
            translation_placeholders={"entity_id": entity_id},
        )

The merge from dev required a few more changes since tests now have shared fixtures.
