v2.6.2 (Lyra): Thema editor, content editor, unified scanEditorFiles

- Thema editor (thema's net zo bewerkbaar maken als plugins):
  bestandsbrowser zijbalk, nieuw bestand, uploaden, verwijderen,
  verplaatsen, SCSS compileren vanuit editor, thema activeren/
  verwijderen, nieuw thema met basis-kopie, uniforme thema-structuur
- Content editor (content consistent met plugins en thema's):
  bestandsbrowser zijbalk naast bestaande lijst weergave, nieuw
  bestand/map, uploaden, verwijderen, verplaatsen, mappen beheer,
  layout/plugins selectie, git/backup integratie in editor zijbalk
- Uniformiteit: scanEditorFiles() unified scanner
  (scanPluginFiles/scanThemeFiles/scanContentFiles als dunne wrappers)
- Media invoegen in editor: ?theme= scope voor media-list endpoint
- Bug fix: thema-naam niet overgenomen bij kopiëren - title in
  theme.json wordt overschreven met nieuwe themanaam
- Handleidingen bijgewerkt (thema-beheer.md + content-beheer.md NL/EN)
- Release notes: docs/release-notes/v2.6.2.md
- Pentest 30/30, WCAG 25/25
