fix(location): truncate long address in memo location chip

The location chip used the kit Button (shrink-0 + whitespace-nowrap),
which grew unbounded so its inner truncate span never fired and long
addresses overflowed the memo card. Replace with a raw button that
caps width (max-w-full min-w-0) and truncates the address text,
matching the existing LocationDisplayEditor pattern.
