fix: @click.away→@click.outside GLOBAL — 16 instances across 5 templates

Alpine 3.x a renommé .away en .outside. Toutes les occurrences dans:
- base.html (3: user menu, context menu, ws ctx)
- page_editor.html (5: share, perm, access, more, gsMore)
- workspaces.html (1: dialog overlay)
- workspace.html (1: modal overlay)
- local_workspace.html (6: create, rename, delete modals, context menus)

Ces .away cassées empêchaient tous les @click Alpine de fonctionner
sur ces pages (Cancel, Delete, et tous les autres boutons modaux).
