ENG-1646: Auto-resize content input and 512 char limit in node creation dialog (Roam) (#985)

* ENG-1646: Auto-resize content input and 512 char limit in node creation dialog (Roam)

- Replace InputGroup with TextArea (growVertically) in create mode for auto-resize
- Add 512 character limit with an inline warning message at the limit

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Apply 512 char limit to edit mode and reduce textarea min-height to 1 line

- Add maxLength and limit warning to edit mode textarea
- Reduce min-height from 96px to 2rem so textarea starts at ~1 line and grows naturally
