Move secret validation logic and authN-loadPrincipal into `PolarisSec…

…retsManager`

The logic _how_ a principal and/or principal secret's are persisted should be transparent to the calling code. Relying on the persistence internals for principals and secrets management makes it impossible to factor out secrets management / make principal management possible.

This change moves the secret validation and retrieval of a principal by client-ID behind an implementation of `PolarisSecretsManager`.
