The controller's buildPageSlug truncates the page title via
`title?.substring(0, 70)` before slugifying, but no test drove that
branch (the only titled case was 16 chars). Add a resolvable-alias
case with a 119-char title whose 70-char boundary falls mid-word and
assert the 302 target's slug reflects only the first 70 characters.
