refactor: move the transports into entryPoints and outputs

The HTTP servers and MQTT command handling go to src/entryPoints/, the
socket emitter and the MQTT and socket output of shades, groups and rooms
to src/outputs/. GLOSSARY.md names what they become once split:
WebUiRoutes, ApiRoutes and MqttCommands in, MqttPublisher and
SocketEmitter out.

Only files and include paths change. esp32devdbg flash goes from
1,546,405 to 1,546,257 bytes.
