feat(source-api): add Codex app server provider

[siisee11]

One-Line Summary

Codex App Server API can now be connected as a Source API provider and used through audited REST operations.

User-Facing Changes

• Adds a Codex App Server API provider to the public provider catalog.
• Allows connecting credentials with apiBaseUrl and apiKey.
• Exposes native /v1/models, /v1/responses, and /v1/chat/completions calls through Source API.

Why This Changed

Velen needs to list and call the Codex app server as an integration worker. The provider catalog previously had Hermes as the closest OpenAI-compatible worker shape, but no distinct Codex app server provider identity or adapter.

How It Changed

• Added codex_app_server_api credentials and catalog metadata.
• Registered a simple REST Source API adapter with Bearer auth and Codex-friendly request headers.
• Added provider icon support and provider snapshot coverage.
