Add WYSIWYG Markdown editor (EasyMDE) to wiki pages

Reusable MarkdownEditor component using EasyMDE:
- Toolbar: bold, italic, headings, quotes, lists, links, images,
  tables, code blocks, preview, side-by-side, fullscreen
- Dark mode support with custom CSS overrides
- Value syncs via bind:value for form submission
- Applied to both wiki new and edit pages
- Replaces the plain textarea + manual preview toggle
