This implements Webauthn. Old devices can be used to authenticate via the appid compatibility layer which should be automatic. New devices will be registered via Webauthn, and devices which do not support FIDO2 will no longer be able to be registered. At this time it does not fully support multiple devices (backend does, frontend doesn't allow registration of additional devices). Does not support passwordless.
This enhances the existing time.Duration parser to allow multiple units, and implements a decode hook which can be used by koanf to decode string/integers into time.Durations as applicable.
This adds an access-control command that checks the policy enforcement for a given criteria using a configuration file and refactors the configuration validation command to include all configuration sources.
This adds method to validate the system clock is synchronized on startup. Configuration allows adjusting the server address, enabled state, desync limit, and if the error is fatal.
