Adds a "Donnée liée" settings group to Texte/Titre: pick an object, optionally match it to the current game state via 1-2 filter conditions (same engine as the data-repeater's filter, including {{Objet.champ}} cross-references), and use {{champ}} in the text content to show a field from that one matching row. Unlike the data repeater — built for showing a list of rows — this covers displaying a single computed value (e.g. the objective of the level matching the game's current parcours/level) without wrapping it in a repeater.
- Merge "Taille dans le conteneur" into "Position & taille": a child
element (posé dans un conteneur/répéteur/groupe de champs) now shows
greyed-out X/Y (not applicable, it follows its parent's layout) and
a single Largeur/Hauteur field per axis with a unit selector (%/px)
instead of the old fixed-px-only sliders capped at 1000 — which was
the root cause of a landscape-mode bug where a child couldn't be
made wider than 1000px even though the actual screen was wider.
New c_size control type (one style key per axis, not two competing
sliders — an earlier px+% two-slider attempt let the untouched
slider silently clobber the other's value on every autosave).
- Merge the two "Disposition" groups (visibility + scale, previously
split apart in UNIVERSAL_CONTROLS by unrelated groups) into one.
- Remove the "Survol" panel: hovering is conceptually a flow trigger,
not a static element property — to be reintroduced there. The
underlying data-hover-text/bindHoverTexts runtime is untouched.
