Surface Drupal messages as small top-right toasts, auto-dismissed

Two problems: (1) the node form's modal AJAX submit handler
(figli_compta_ledger_node_form_ajax_submit) closed the dialog on
success without ever surfacing whatever messenger() had queued during
save() -- e.g. NodeForm's own "Ligne comptable X has been updated."
Since the /lignes table only ever refreshes via AJAX afterwards, never
a full page load, that message was silently lost instead of just
delayed. Now forwarded via MessageCommand before closing the modal.
(2) Gin's default message styling is a full-size flash banner meant
for a single admin form, in-flow (pushing the page down) and far too
large for frequent background feedback on this dashboard.

admin-chrome.css repositions [data-drupal-messages] /
[data-drupal-messages-fallback] to fixed top-right (out of document
flow, so nothing shifts) and shrinks text/padding/dismiss-button size
drastically while keeping them legible. admin-chrome.js auto-dismisses
non-error messages after 2s via a MutationObserver (Drupal.Message.add()
just appends a DOM node, it never re-fires attachBehaviors(), so
behaviors/once() would miss anything added after the initial page
load); error messages are left alone, requiring the existing manual
click on Gin's own dismiss button. Both attached globally via the
existing admin_chrome library (already loaded on every page for the
phantom-top-bar fix), consistent with that precedent.

Verified: a real full-form save on a clean node returns exactly
{message (status, "has been updated"), closeDialog} in that order: a
répartition-inconsistent node still correctly blocks the full form
(unaffected, skip_validation is never used here); a synthetic
status/warning/error trio confirms fixed positioning, no layout
shift, ~40% smaller text, and status/warning auto-hiding while error
persists until manually dismissed.

/* Drupal status messages: fixed top-right, out of document flow, so they
never shift the page layout the way the default in-flow placement does
-- and shrunk to a fraction of Gin's default size, which is sized for a
single full-width flash banner on an admin form, not a toast for
frequent background feedback here. Targets both the real region
([data-drupal-messages], present once a message is queued on a normal
page load) and the JS-only fallback container
([data-drupal-messages-fallback], used when Drupal.Message.add() -- our
own MessageCommand-driven AJAX messages included -- has no region to
attach to). Auto-dismiss timing for non-error messages is handled in
admin-chrome.js. */
