fix(http): decompress gzip-encoded git request bodies

Modern git clients send Content-Encoding: gzip on POST requests to
/git-upload-pack for efficiency. Without decompression, the compressed
binary data was passed directly to git upload-pack, which expected
pkt-line format, causing:

  fatal: protocol error: bad line length character: ??
  error: RPC failed; HTTP 500

This was discovered in production when git clone requests consistently
failed with HTTP 500 errors. The fix extracts the Content-Encoding
header and uses flate2::GzDecoder to decompress gzip bodies before
passing them to the git subprocess.
