Fixes #108: Move json.dumps closing parenthesis to apply quote removal
after JSON serialization instead of before. This prevents duplicate
quotes in AP names that prevent config sync in Central.

Changes line 126 from:
  json.dumps(row[1].replace('"', ''))
to:
  json.dumps(row[1]).replace('"', '')

Fixes #17: The webserver was not returning control to the requestor
because rfile.read() without a length argument blocks until EOF.

Use the Content-Length header to read exactly the expected number of
bytes, allowing the server to return control properly.

Changes line 71 from:
  body = self.rfile.read()
to:
  body = self.rfile.read(int(self.headers['Content-Length']))
