Server responds with invalid `accept-range` header

[piotr-cz]

I'm trying to resume a partial download, but it doesn't work:

• response contains accept-range: bytes header instead of Accept-Ranges
• requesting partial content results in 200 OK status code and full payload instead of 206 Partial Content and partial payload

Reproduction:

curl -s -r 0-99 -o NUL -D - https://nodejs.org/dist/v24.14.0/node-v24.14.0-linux-x64.tar.xz

Pr up fixing the accept-ranges header, since it's a cache hit I'm assuming range header not being respected is another issue with the workers tiered cache but will confirm (I did confirm r2 is getting the range at least in the worker code)
