Enhance DALI device type discovery and query handling

- Introduce DaliDeviceTypeDiscovery struct for managing device type queries.
- Implement discoverDeviceTypes method in DaliBase for improved device type detection.
- Update DaliComm to handle query responses more robustly, including handling multiple device replies.
- Add setDetectedDeviceTypes method in DaliDevice to manage detected device types and capabilities.

 ## Notes
 
-- Optional query support: provide a `transact` callback that returns the gateway reply; otherwise, query methods return `std::nullopt`.
+- Query support works with either a `read` callback or a `transact` callback. When `read` is available, queries return as soon as the reply bytes arrive instead of waiting behind a fixed pre-read delay.
 - `Dali` facade in `include/dali.hpp` mirrors `lib/dali/dali.dart` and wires `base`, `decode`, `dt1`, `dt8`, and `addr` together.
 - The `t`, `d`, and `g` parameters in Dart are not required here; timing/gateway selection is driven by your callbacks.
 - `DaliCloudBridge` now uses the shared bridge engine internally, so MQTT downlinks can target either raw DALI frames or registered bridge models.
