Add quote indicator and distinct callout styling for Note/Tip/Warning/Important

- Description editor: blockquotes get a left accent line and muted color so
  it's clear when typing in "quote mode" (matches the existing active Quote
  toolbar button highlight).
- Editor block cards: each text block's left border is colored by its level
  (info/success/warn/error) so Note/Tip/Warning/Important are distinguishable
  at a glance.
- PDF/HTML/DOCX exports: callouts now get a level-specific accent color and
  tinted background/shading (blue/green/amber/red), instead of all looking
  identical except for the label text.
