Enhance QuickPost: auto-expand height, numbered list autocomplete, discard confirmation

- Text area auto-expands from 5 to 12 rows as user types, driven by
  layout manager content height calculation
- Numbered list autocomplete (1. → 2. → 3.) with empty item cancellation
- Cancel button shows discard confirmation when post has content
