Rich text editor: lists missing bullets/numbers, link fails silently, code button unnecessary

Three issues with the Tiptap RichTextEditor (comment editor): **1. Bullet and numbered lists don't show bullets or numbers**\ When you toggle the bullet list or ordered list, the text gets indented but no bullet points (•) or numbers (1. 2. 3.) are rendered. The list is structurally there (HTML has <ul>/<ol>) but the CSS is missing list-style-type. Likely a Tailwind CSS reset stripping list styles. **2. Link option fails silently on invalid URLs**\ If you enter an invalid URL in the link dialog (e.g. just "hello" instead of "https://..."), it silently does nothing — no error message, no feedback. Should show a validation error like "Please enter a valid URL". **3. Code button is unnecessary for comments**\ The <> code toggle doesn't make sense in a comment/event description context. This isn't a developer tool. Consider removing it from the toolbar, at least for the compact comment preset.
