When a deleted peer tries to reconnect, GetUserIDByPeerKey was returning
Internal error instead of NotFound, causing clients to retry indefinitely
instead of recognizing the unrecoverable PermissionDenied error.
This fix:
1. Updates GetUserIDByPeerKey to properly return NotFound when peer doesn't exist
2. Updates Sync handler to convert NotFound to PermissionDenied with message
'peer is not registered', matching the behavior of GetAccountIDForPeerKey
Fixes the regression introduced in v0.61.1 where deleted peers would see:
- Before: 'rpc error: code = Internal desc = failed handling request' (retry loop)
- After: 'rpc error: code = PermissionDenied desc = peer is not registered' (exits)
Embed Dex as a built-in IdP to simplify self-hosting setup.
Adds an embedded OIDC Identity Provider (Dex) with local user management and optional external IdP connectors (Google/GitHub/OIDC/SAML), plus device-auth flow for CLI login. Introduces instance onboarding/setup endpoints (including owner creation), field-level encryption for sensitive user data, a streamlined self-hosting provisioning script, and expanded APIs + test coverage for IdP management.
