fix: button rendering from RichEditor to markdown to HTML

Browse Source 
- Added multiple htmlToMarkdown patterns for TipTap button output:
  1. data-button with data-href/data-style attributes
  2. Alternate attribute order (data-style before data-href)
  3. Simple data-button fallback with href and class
  4. Buttons wrapped in p tags (from preview HTML)
  5. Direct button links without p wrapper

- Button shortcodes now correctly roundtrip:
  RichEditor -> HTML -> [button url=... style=...] -> Preview/Email

- All patterns now explicitly include style=solid for consistency
