Add a macro recorder: record a task by hand, for an assistant to script

Projet > Scripts > Enregistrer une macro (also in command search and the
shortcut bar) records what is done on the current project until clicked
again. Under <data folder>/recordings/<id>/ it saves the whole project
before and after, the folio and selection at the start, and each step from
the undo history -- its name, the commands inside it, the folio, what was
selected, and the folio after it. No editing command is taught to the
recorder, and nothing new walks the scene: the files are QElectroTech's
own serialisation.

While recording, the status bar shows "● Enregistrement : N étapes" with
Arrêter. At the end a box says where it went and offers "Copier la demande
pour l'assistant": a ready-made request naming the recording, to paste
into the assistant's chat, since QElectroTech cannot send it anything
itself. qet-assistant.json lists the recordings, and live status says
whether one is under way and which was last.
