Reclaim broken backlinks (part 2): 32 more 301 redirects

Follow-up to the initial broken-backlink PR. Adds 32 more 301 redirects for
docs.tigera.io/calico paths surfaced by the full tigera.io subdomain backlink
export that the first pass (24 redirects) didn't cover. Each broken URL maps
1:1 to the most relevant live page; where a feature was removed, it points to
the nearest relevant page or section landing (never the homepage). Ordered by
referring-domain rating.
