feat: inline designer undo/redo SVGs in CCB with currentColor

- Replace the fa-rotate-left / fa-rotate-right glyphs on #ccbUndoBtn /
  #ccbRedoBtn with inline designer SVGs (src/styles/images/{undo,redo}.svg).
- Drop the designer asset's hardcoded fill/stroke colors; use fill:
  currentColor only so the icons inherit .ccb-btn color (hover/active
  follow free). No bg-coupled stroke — keeps the asset and stylesheet
  free of themed hardcodes.
- Render at 15x11 via CSS (.ccb-edit-icon) to match the visual weight
  of the surrounding CCB icons without needing the old stroke trim.
