## Summary
- After a successful `uninstall`, clear all app registration config
(`appRegistrationId`, `appRegistrationClientId`, `appAccessToken`,
`appRefreshToken`) so the next `dev` run doesn't hit "app not found"
errors from leftover credentials
- On app re-registration (`ensureAppRegistration`), clear stale
`appAccessToken`/`appRefreshToken` that belonged to the previous
registration
- On OAuth token refresh failure, only clear config when the server
returns `invalid_client` (registration was deleted), not on transient
failures like network issues
- Extract a shared `parse-server-error` utility for consistently parsing
both GraphQL error codes (`extensions.code`/`subCode`) and OAuth error
responses (`error`/`error_description`)
