fix(measure): task_execute full-screen layout + hide UI for tasks without measurements

Pagina /measure/execute/<task_id>:
- Il pannello destro (info subtask + tolerance + numpad) e la sidebar
  marker spariscono quando il task non ha subtask: l'utente vede solo
  intestazione + disegno a tutta larghezza, senza colonne vuote né
  tastierina numerica fuori contesto.
- Risolta la scrollbar verticale: la pagina ora occupa esattamente
  l'altezza del viewport. Il layout sfrutta nuovi block override in
  base.html (body_class, wrapper_class, main_class, footer) per
  disattivare scroll e footer solo su questa pagina, lasciando intatte
  le altre.

Cataloghi i18n: aggiunte traduzioni EN/IT mancanti e rimossi i flag
"fuzzy" auto-generati da pybabel update (Flask-Babel ignora i fuzzy,
mostrando il msgid italiano anche in EN).
