## Summary
- Adds an `authType` field (`'api_key' | 'access_key' | 'iam_role'`) to
AI provider config
- Providers like Amazon Bedrock that authenticate via IAM role (instance
profile) can now be registered without explicit API keys or access keys
- Backend: `isProviderConfigured()` checks `apiKey || accessKeyId ||
authType`
- Frontend admin panel: shows green "Configured" badge and "IAM role"
description for providers with `authType: "iam_role"`
- Provider detail page shows "IAM role (instance profile)" in the
credentials row
## Companion PR
- twentyhq/twenty-infra#528 — patches `authType: "iam_role"` into
dev/staging Bedrock catalogs
## Changed files
- **Backend**: new `AiProviderAuthType` type, `isProviderConfigured`
util, updated registry + resolver
- **Frontend**: new `AiProviderAuthType` type, updated provider list
card + detail page
## Test plan
- [ ] Deploy with a Bedrock catalog that includes `"authType":
"iam_role"` — verify Bedrock shows "Configured" in admin AI panel
- [ ] Verify OpenAI/Anthropic with `apiKey` still show "Configured"
- [ ] Verify a provider with no credentials and no `authType` still
shows "No credentials"
