* test: cover TurboQuant, turbo4 datatype and keyword prefix in compat data
Extend the storage compatibility fixture with vector and payload index
features that landed since the generator was last updated:
* TurboQuant quantization, one collection per persisted blob layout
(bits1_5 and the default bits4)
* the turbo4 storage datatype, on both dense and multivector storage
* the keyword index `prefix` option, plus a matching prefix scroll in the
query battery
Sparse vector configs reject the turbo4 datatype, so create_collection omits
the sparse datatype for that collection rather than forwarding it. This is a
no-op for every other collection.
Archives are generated once per release and keep the collection set of their
own generation, so expected collections are now resolved per version and the
new ones are only required from v1.19.0 onward. The prefix scroll stays
ungated: archives without the prefix index answer it by scanning.

* test: fail instead of skip when a compatibility archive is missing
A 404 from the compatibility bucket means the archive was never published,
which no amount of retrying fixes. Skipping it reported the version as
covered while nothing ran, so a pull request adding a version could stay
green with its new coverage never executing.
Fail on 404 and keep skipping connection resets and timeouts, so a bucket
outage still does not turn unrelated pull requests red.
