refactor: split the transports into the modules GLOSSARY.md names

Code moves unchanged; only files and names change.

- entryPoints/WebUiRoutes.cpp: registerWebUiRoutes(), the port 80 routes
  and the UI's files, with the helpers only they use.
- entryPoints/ApiRoutes.cpp: registerApiRoutes(), the port 8081 routes.
- entryPoints/Web.cpp keeps the servers' lifecycle, auth and the handlers
  both route sets call; entryPoints/WebRoutes.h is what the three share.
- entryPoints/MQTT.* -> MqttConnection.*, class MQTTClass -> MqttConnection.
- outputs/SomfyMqtt.cpp -> outputs/MqttPublisher.cpp.
- outputs/Sockets.* -> outputs/SocketEmitter.*.

The subscribe and unsubscribe lists (the latter repeated
groups/+/direction/set) become MqttCommands' MQTT_COMMAND_TOPICS, and a
native test checks the parser takes every topic in it. GLOSSARY.md gains
MqttConnection and Change fan-out.

328 native tests. Flash: esp32devdbg +3,112 bytes (the routes are a second
ArduinoJson file), esp32dev -2,336 bytes.
