Visore <tmf-viewer> di TieVision-Station con no-layers su ogni immagine di TMF (#126)

Rotella senza Ctrl = zoom sul punto del mouse su tutte le immagini. image_viewer.js e
vision_overlay.js copiati byte per byte da TieVision-Station (lavoro/daitarn-nolayers b1af911);
attributo no-layers su ogni <tmf-viewer> (task_editor 3, task_execute 1, calibrazione_pagina 4).
Test JS e pagina demo allineati.

+/**
+ * image_viewer.js - #122: <tmf-viewer>, il visualizzatore immagine standard di TieMeasureFlow.
+ *
+ * Cosa fa: Custom Element in JS puro (senza Alpine ne' Tailwind) con zoom -/+, Adatta, Salva, percentuale,
+ *          rotella (e Ctrl+rotella) intorno al puntatore, pan col puntatore, overlay SVG a tratto costante ed etichette,
+ *          menu dei livelli in alto a sinistra (#12).
+ *          Sostituisce le quattro implementazioni di zoom di prima (pannello operatore #115, wizard DXF #113 e #104,
+ *          pagina camera #111). Light DOM, stile iniettato una volta nel <head> (<style id="tmf-viewer-css">).
+ * Come si usa: <script> vision_overlay.js e save_image.js, poi image_viewer.js; poi
+ *          <tmf-viewer src="..." width="1920" height="1080" save-name="task_14" fit-height></tmf-viewer>
+ *          Attributi: src, width, height (px logici), save-name, save-src, no-save, fit-height,
+ *          label-fit, label-save, title-in, title-out, title-save.
+ *          Senza src, un figlio <svg> (DXF) va nello stage al 100 % (modo contenuto; Salva lo rasterizza in PNG).
+ *          Proprieta': overlay (forme vs-tools -> VisionOverlay.svg), labels ([{key,x,y,text,cls}] in px logici),
+ *          zoom (sola lettura); metodi fit(), zoomBy(f). Eventi (bubbling): viewer-load {width,height}, viewer-zoom {zoom,fit}.
+ *          #12 livelli: la rotella senza Ctrl zooma sul punto del mouse. L'overlay sta in tre gruppi SVG
+ *          (<g data-layer>): ricerca, costruzioni (opacity 0.5), quote; un menu a caselle (.tmfv-layers) accende
+ *          Immagine, Costruzioni, Ricerca (spenta di default), Quote, Nomi. #126 attributo no-layers = viewer semplice, come
+ *          prima dei livelli: niente menu, un solo disegno (VisionOverlay.svg di tutte le forme, poi le quote), nessun <g data-layer>
+ *          ne' opacity, forme e immagine sempre visibili, etichette sempre accese (text) e non trascinabili (niente quota-spostata);
+ *          zoom con rotella, pan, Adatta e Salva restano. Lo stato dei livelli non conta con no-layers. Proprieta'
+ *          layers get/set {immagine,costruzioni,ricerca,quote,nomi}, evento viewer-layers {layers}; stato in localStorage
+ *          (chiave tmf-viewer-layers[:save-name]). Etichette estese: {key,x,y,text,breve,cls,nome,camera,quota,testo};
+ *          con quota stanno sul punto della scritta (VisionOverlay.quotaPunto) e si trascinano: evento quota-spostata
+ *          {key,nome,camera,testo:[du,dv]|null} (doppio clic = testo null, posizione di default).
+ *          In Alpine: :src="...", x-effect="$el.overlay = ...; $el.labels = ...".
+ * Dipende da: window.VisionOverlay (facoltativo, per l'overlay), tmfSaveImage/tmfSaveBlob/tmfSvgToPngBlob di save_image.js
+ *          (per Salva). Il modulo si carica anche in node (require): esporta solo TmfViewerMath, funzioni pure.

+ * save_image.js - #119: salva il frame grezzo mostrato nel pannello visione come PNG, senza disegni.

+ * Cosa fa: tmfSaveImage(src, baseName) scarica l'immagine `src` (blob: o http), la converte in PNG se serve
+ *          e la salva con nome <baseName>_<AAAAMMGG-hhmmss>.png: «Salva con nome» (showSaveFilePicker)
+ *          dove c'e', altrimenti <a download>. Ritorna una Promise<boolean> (false se annullato o fallito).
+ *          tmfSaveImageName(baseName, date) e' la funzione pura del nome, esportata per i test.
+ * Come si usa: <script src=".../save_image.js"></script> poi @click="tmfSaveImage(url, 'task_14')".
+ * Dipende da: fetch, canvas, createImageBitmap e window del browser, toccati solo dentro le funzioni
+ *          (il modulo si carica anche in node, con require, senza questi globali).
+ *          #122: tmfSaveBlob(blob, baseName) salva un blob PNG gia' pronto; tmfSvgToPngBlob(svgEl, w, h) rasterizza un <svg>
+ *          (sfondo bianco, lato lungo 1600-4096 px). Entrambi usati da <tmf-viewer> (image_viewer.js).
