feat(02-05): add 15 Phase 2 localization keys to EN/FR resx and Designer

- Added 15 keys to Strings.resx with English values (grp.scan.opts, chk.scan.folders, chk.recursive, lbl.folder.depth, chk.max.depth, chk.inherited.perms, grp.export.fmt, rad.csv.perms, rad.html.perms, btn.gen.perms, btn.open.perms, btn.view.sites, perm.site.url, perm.or.select, perm.sites.selected)
- Added same 15 keys to Strings.fr.resx with genuine French translations (no English fallback)
- Added 15 static properties to Strings.Designer.cs following dot-to-underscore naming pattern
