feat(auth): support configurable CLI device flow

[a2bondar]

Dependency

Depends on #2227. Merge that pull request first. This pull request is intentionally stacked on it and should target main after the dependency lands.

Summary

Make CLI OIDC device login and token refresh interoperable with providers that use a dedicated public client, a different bearer-token response field, or provider-specific device request parameters. Standards-compatible behavior remains the default.

Changes

• Add a dedicated optional CLI client ID and publish it through auth discovery.
• Support configurable bearer-token selection for login and refresh without silently falling back to another token type.
• Add opt-in device metadata and configurable scope handling for token polling.
• Persist a stable local device identifier with restricted permissions when enabled.
• Serialize refresh, reload shared credentials, and safely persist rotated refresh tokens.
• Replace provider-specific refresh-token guidance with provider-neutral messaging.
• Update configuration reference, OIDC documentation, OpenAPI output, and focused tests.

Type of Change

• Code change with documentation updates

Quality Gates

• Tests added or updated for changed behavior
• Documentation updated for user-visible behavior

Verification

• uv run pre-commit run -a passes, or any blocked checks are identified below
• Targeted tests pass, or tests are marked not applicable above

• Full-repository pre-commit was not run; targeted checks are listed above.

Summary by CodeRabbit

• New Features
  • OIDC authentication can use access tokens or ID tokens for API requests.
  • CLI login supports a dedicated client ID and configurable device-flow options, including persistent device IDs, display names, and scope handling.
  • Studio renews ID tokens before they expire and retries after failed renewals.
  • Token expiry is retained across reloads, including for opaque tokens.
• Bug Fixes
  • Device-login errors provide clearer details, and token refresh failures—including failures to save rotated refresh tokens—are handled more reliably.
  • Invalid authentication discovery data and malformed stored tokens are handled more reliably.

📝 Walkthrough

Walkthrough

OIDC discovery adds CLI client and device-flow settings. CLI and client authentication support configurable bearer-token sources and persisted expiry. Studio schedules and retries silent ID-token renewal.

Changes

OIDC authentication and token lifecycle

Layer / File(s)	Summary
OIDC configuration and discovery packages/nhx_common/src/nhx/common/config/base.py, services/core/auth/..., openapi/*, docs/auth/authentication/oidc.mdx, docs/set-up/config-reference.mdx, packages/nemo_helix_ext/src/nemo_helix_ext/auth/helpers.py	Configuration, discovery responses, OpenAPI schemas, and guides add CLI client ID, bearer-token source, and device-flow settings.
CLI device flow and login packages/nemo_helix_ext/src/nemo_helix_ext/auth/device_flow.py, packages/nemo_helix_ext/src/nemo_helix_ext/cli/commands/auth.py, packages/nemo_helix_ext/tests/auth/*, packages/nemo_helix_ext/tests/cli/commands/test_auth*.py	Device flow supports persistent device IDs, optional display names, configurable polling scope, and updated HTTP error handling. CLI login uses discovered settings and saves token expiry.
Token expiry and refresh persistence packages/nemo_helix_ext/src/nemo_helix_ext/{auth/token_provider.py,config/models.py,client/bootstrap.py}, packages/nemo_helix_plugin/src/nemo_helix_plugin/client/*, related tests	Token providers support configured bearer fields and expiry restoration. CLI and client configuration paths persist expiry; rotated refresh-token persistence failures are surfaced. Discovery fallback is limited to HTTP and JSON decoding errors.
Studio ID-token renewal web/packages/sdk/src/utils/oidcBearerToken*, web/packages/studio/src/{App.tsx,providers/auth/OidcIdTokenRenewal*}	The SDK extracts ID-token expiry. Studio schedules silent renewal 90 seconds before expiry, or immediately if that time has passed. Failed renewals retry after 15 seconds, and cleanup cancels pending retries.

Priority: ➖ Normal

Change: Feature

Merge Risk: 🟡 Moderate · up to 19468

A malformed token lifetime from the identity provider, or a bad expiry in the config file, can leave the CLI and SDK sending an expired token without refreshing, which blocks authenticated requests until the credentials are fixed. An unsupported bearer-token setting from the server can also let commands continue with an expired token instead of prompting a new login. Both fixes are small and should land before merge.
