Port the Mac app's scene system to the phone control. Each queue entry is
now an independent clone carrying a `cues` list of timed elements (effect /
text / image), each with its own appearance time and visible duration; the
three channels are driven independently from playback progress (advanceCues).
Add visual-only "Intermezzo" queue items (silence audio, run their scene for
a set duration) and make the inter-track gap keep the scene running. New
mobile scene editor lives in the queue card detail (⚙). The queue (with
scenes) is persisted via saveState so it survives a phone reload.

- Queue cards expand to a detail panel with the waveform, elapsed/total/remaining
times, draggable in/out handles, scrub-to-seek and a 'pausa dopo' gap.
- /api/peaks now also returns exact duration (samples/8000) so non-playing tracks
have correct times/trim without relying on the output media probe.
- Service worker switched to network-first (+v2) so UI updates aren't masked by
a stale cache; output.js probeDurations hardened (load()+timeout fallback).

New separate project (the Electron Mac app stays untouched). Reuses the visual
engine (WebGL shaders, effect catalog, Web Audio) verbatim and replaces Electron
IPC with a Node HTTP+WebSocket server:
- server.js: serves the kiosk output page + mobile control PWA, relays the same
ctl/rpt JSON protocol over WebSocket, plus REST for media library/upload,
JSON state (pads), waveform peaks and MP4 recording (ffmpeg).
- public/js/net.js: window.djv shim over WebSocket+HTTP so output.js runs intact.
- public/index.html + control.js: touch-first mobile remote (effects, media/queue,
ticker, pads, audio/EQ, fullscreen + recording).
- PWA (manifest + service worker + generated icons).
- scripts/: Chromium kiosk launcher + install-pi.sh (systemd units for Pi 5).
Verified: REST endpoints, WebSocket relay both directions, control PWA loads the
2958-effect catalog and renders. (Headless WebGL output not testable without GPU.)
