Move 9 business-logic modules from the backend root into services/: channels, effects, history, profiles, stories, versions, export_import, transcribe, tts. Move platform_detect.py into utils/. Backend root now contains only infrastructure (app, main, config, server, models, build_binary) and docs. All 94 routes verified.
