Wrap Access and Modifiers columns in <code> tags

Add CodeWrapArrow helper that wraps values in <code> tags, handling
the "old → new" arrow format as <code>old</code> → <code>new</code>.
Applied to Access and Modifiers columns in the semantic changes detail
table (HTML report only; semantic changes are excluded from MD report).
Updated all sample base64 blocks.
