JSON rendering for production errors via the API and for Phoenix error responses.

This module serves dual purpose:

- Renders error/occurrence data for the /api/v1/errors endpoints
|
|
- Renders generic error responses (404, 500, etc.) for the Phoenix endpoint

when the request accepts JSON (configured in config/config.exs render_errors)
