This commit makes modifications to the OIDC request handlers to return appropriate gRPC
status codes on errors. Before this change, boundary presents the internal error codes to
clients. This causes problems for reverse proxies, as these status codes are mapped to
non-standard HTTP response codes which are ultimately all turned into 500 responses when
4xx status codes are more appropriate and descriptive of the error returned.
Some modifications in this commit include calls to `event.WriteError` so that the
internal error is written to the controller log for visibility. Comments about
potential duplicate logs are now removed as `event.WriteError` is not called when using
functions from the `handlers` package.
