v2.6.1d (Lyra): Plugin i18n, plugin editor vernieuwd, media invoegen

Plugin internationalisatie: plugins hebben eigen language/ mappen. Systeem
plugins volgen admin taal (admin.php), content plugins volgen content taal
(site.php). Fallback chain: geselecteerd -> plugin default_language -> CMS
default. PluginManager/AdminPluginAPI/CMSAPI uitgebreid met
getPluginTranslations()/t(). plugin.json settings ondersteunen
label_key/help_key/option_label_key.

Plugin uniformiteit: alle 6 plugins hebben uniforme structuur (README.md,
assets/.gitkeep, language/nl|en/). plugins/README.md herschreven.
guide plugin-development.md (NL+EN) volledig herschreven.

Plugin editor vernieuwd: geneste bestandsbrowser zijbalk, nieuw bestand
aanmaken, uploaden naar assets/, verwijderen en verplaatsen. Nieuwe routes:
plugins-file-upload, plugins-file-delete, plugins-file-move. Path-traversal
bescherming + protected plugins geblokkeerd.

Media invoegen in editor: nieuw /admin/media-list JSON endpoint + herbruikbare
_media-modal.twig include. Plugin-context scant assets/ map. editor-toolbar.js
modeMap uitgebreid voor css/scss/js/json.

Plugin overzicht knoppen: alleen iconen met title/aria-label.

Tests: pentest 30/30, WCAG 2.1 AA 25/25.
