Restore footer consultation link (revert footer dedupe)

Per review, keep both footer consultation CTAs rather than collapsing to
one: the global footer Resources column gets its booking link back
alongside the per-doc consultation card. Restored in sentence case
("Book a complimentary assessment") to match the sentence-case
normalization applied to the other CTA labels in this PR.
