Missing Bearer in header authorization?

[psyclaudeZ]

According to the wire spec, Bearer shall be part of the generated auth header, but it's not the case based on the current implementation:

conjure-python/conjure-python-core/src/main/java/com/palantir/conjure/python/poet/PythonEndpointDefinition.java

Lines 147 to 149 in e835236

	if (param.pythonParamName().equals(AUTH_HEADER_PYTHON_PARAM_NAME)) {
	poetWriter.writeIndentedLine("'%s': %s,", headerParamId, param.pythonParamName());
	} else {

I drafted #981, but I understand the change could be breaking. Just would like to put it on the radar.
