Close HTTP response bodies when loading compressed HTML

[bensynapse]

I run Live Tennis API.

LoadURLWithClient closes the selected decompressor, which leaves the underlying HTTP response body open. Invalid compression and unsupported encodings also return without closing the body.

Close the response body after every successful client.Do call and close each decompressor separately. Plain responses still close once.

The regression test covers plain, gzip and deflate responses, invalid compression, unsupported encoding and a read failure. Successful cases also verify the parsed document.

Checks passed on Linux:

• go test . -v -cover on Go 1.23.4 and 1.24.2.
• go test -race ./... on Go 1.23.4.

Both coverage runs report 73.6%. go vet ./... reports an existing testing.T.Fatalf call from a goroutine at query_test.go:210. The unmodified upstream commit reports the same warning.
