fix: restore the Results and Download tabs, and stop two tests failing in CI

More of what "Remove Overlay feature, feedback, and revert to old site"
took off the public site along with the curator build.

  Download tab   restored. Offers PNG, JPEG, PPTX, GIF, SBML, SBGN,
                 BioPAX2/3, PDF and Newt, and renders correctly.
  Results tab    restored. With an analysis running it shows the
                 overrepresentation table -- pathway, matches, entities
                 found and total, p-value -- and holds up when identifiers
                 are not found, which is the case that exercises
                 not-found-table.
  Thumbnail      restored in the diagram; the image loads.
  Expression tab left commented. It renders empty even against a
                 quantitative analysis with expression values, so unlike
                 the others it looks genuinely unfinished rather than
                 merely hidden. Not worth shipping a blank tab.

Restoring the Download tab means the exporter block added at Apache last
night now breaks a visible feature; ~/allow-user-downloads.sh switches
that rule from "block everything" to "allow from our own pages", which
keeps crawlers out and gives the buttons back.

Two CI failures, both mine, both from CI running against reactome.org
while beta runs against the dev content service:

  The locations test assumed /locationsInPWB exists. Production answers
  404 for every id on that endpoint -- it does not implement it at all --
  so the test now probes and skips, like the other content-endpoint tests.

  I also have to correct the previous commit's reasoning: it argued the
  rat entity's 404 was fine "because production 404s too". That proved
  nothing, since production 404s for everything there. The conclusion
  still holds, but on the Neo4j evidence -- no hasEvent parent -- not on
  that comparison.

  The species test clicked the dropdown and waited a fixed 1.5s. The
  selector matches the toggle plus one div per species, so on a slower
  runner it read the page before the list opened and reported all 16
  missing. It now waits for the list.

50 unit, 55 e2e (1 skipped).
