fix(editor): v1.19.3 — fit-to-width on open + form-field names accept spaces

A) The continuous view started at zoom 1.0 (fitMode=null) → an A4 page sat small
in a wide canvas ("la taille du formulaire est pas bonne, ça doit occuper tout
l'espace"). Default fitMode to 'width' so the scroller computes fit-to-width from
its live viewport on open; a manual zoom still clears fitMode upstream.

B) The form-field name validator was /^[A-Za-z0-9_.-]+$/ which rejected spaces —
but a partial AcroForm /T name is a PDF text string ("NAIS ENF 5", "Prénom",
"Nom d'usage" are all valid). Broadened to /^[^\p{Cc}]+$/u (non-empty, no control
chars); FR/EN error message updated to the empty-name case.

+
+### Fixed — document fills the canvas on open; form-field names accept spaces
+
+- **The page now fits the width of the editor as soon as a document opens**, instead
+  of showing at 100 % (a small A4 sheet floating in a large empty canvas). The
+  continuous view computes the exact fit-to-width zoom from its live width; a manual
+  zoom still takes over from there.
+- **A form field can be named with spaces (and accents).** The name validator wrongly
+  rejected `NAIS ENF 5`, `Prénom`, `Nom d'usage`… — a PDF field name is a text
+  string, so spaces and punctuation are valid. Only a truly empty name is refused now.
+
 ## [1.19.2] - 2026-07-02
 
 ### Fixed — no more vanishing footer lines or misplaced headers on dense forms
