refactor(openai): share resource and embedding policy

[marandaneto]

💡 Motivation and Context

The sync, async, and Azure OpenAI clients repeated the same resource discovery and replacement logic. Sync and async embedding wrappers also built the same telemetry properties separately. These copies could drift when OpenAI adds resources or embedding telemetry changes.

This refactor shares resource installation through explicit wrapper maps and uses a private helper for common embedding event construction. Provider dispatch and sync or async API calls remain in their existing adapters.

💚 How did you test it?

• uv run pytest --verbose --timeout=30 posthog/test/ai/openai: 79 passed, 1 skipped
• make public_api_check
• Ruff formatting and lint checks on changed files
• Autoreview against origin/main: clean

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes.
• I updated the docs if needed.
• No breaking change or entry added to the changelog.

If releasing new changes

• Ran sampo add to generate a changeset file

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Pi and Slopo identified the duplicated OpenAI resource and embedding paths. The resource-wrapping test now consumes the production wrapper maps so it detects mapping drift. Static type-only assignments remain because the enforced public API snapshot records those dynamically installed class attributes.
