Add query-param fallback to analytics ignore check

[Gutts-n]

What changed

Added ANALYTICS_IGNORE_QUERY_PARAM alongside the header/values/IP checks.
A request whose query string carries this param with a matching value
(from the same ANALYTICS_IGNORE_VALUES list) skips analytics logging the
same way - any one of the four checks (header, query param, IP) is enough.

Why

Part of the NESO API-usage-metrics work (neso-nextgen-shared#152). The
admin portal's resource-download buttons render plain <a href target="_blank"> links to /datastore/dump/{resource_id} - a browser
navigation, not a fetch() call, so no custom header can be attached at
all (browsers don't allow it). The admin portal already sends
Request-Source: admin-portal on every fetch()-based call
(datopian/dx-helm-neso#75); this closes the one gap that was flagged but
left open in that PR - the download links can carry the same value as a
query param instead (?request_source=admin-portal), since that's just a
URL, no header machinery needed.

Verified

• pytest - 490 passed.
• ruff check / mypy - clean.
• New tests exercise the real use case directly: a /datastore/dump/...
  request with ?request_source=admin-portal is not recorded; the same
  URL without the param still is.

Not verified: the admin portal side (building the query param into the
download link) is a separate change in dx-helm-neso, not done yet.
