feat(opapi): generate better error IDs

[AbrahamLopez10]

This PR makes the following improvements for the error IDs we generate:

• The embedded timestamp is now in YYYYMMDDHHMMSS format (UTC time) instead of a Unix epoch timestamp. This is safe to do as a 32-bit crypto-random suffix is added to the error ID which will still provide sufficient protection against error ID collisions on the same second.
• If the error occurs in a browser environment, the prefix for the error ID will be err_bwsr instead of err, so we can easily identify errors that happened in the user's browser, so we can look them up in Sentry instead of Grafana.
