Add AI/ML API as an OpenAI-compatible provider preset

[D1m7asis]

Proposal

Add AI/ML API as a branded provider preset on top of Zoo Code's existing OpenAI-compatible provider path.

The minimal scope would be:

• provider id/label: aimlapi / AI/ML API
• API key field backed by AIMLAPI_API_KEY
• fixed base URL: https://api.aimlapi.com/v1
• bearer authentication through the existing OpenAI-compatible handler
• a small curated chat-model list for the first PR
• attribution headers on AI/ML API requests:
  • X-AIMLAPI-Partner-ID: Zoo-Code-Org
  • X-AIMLAPI-Integration-Repo: Zoo-Code-Org/Zoo-Code
  • X-AIMLAPI-Integration-Version: 1.0.0

Why this fits the current architecture

OpenAICompatibleHandler already accepts a fixed baseURL, API key, model id, and custom headers, so this should not require a new transport or inference implementation. The first version can avoid live model discovery and reuse the existing provider settings/model-picker patterns.

I can prepare the focused implementation, UI wiring, tests, and docs. Would maintainers accept a branded preset with this scope?
