docs: allow long links to wrap per character to prevent page overflow

Some documentation pages contain long link text without natural
break points, which can force page-wide horizontal scroll overflow
on small screens.

Use overflow-wrap: anywhere for anchor text in the docs stylesheet so
links can wrap per character as a fallback when normal word boundaries
are unavailable.

Examples:
