fix(presenter): set the Wayland app_id so the session window gets its icon

Browse Source 
SDL_APP_ID = io.unom.Punktfunk — compositors match it against the shipped
.desktop for the window icon; without it KWin/mutter show the generic Wayland
icon (field-noticed on the Deck). Linux analog of win32 AppUserModelID.
