PQL: Add env mapping for OpenAI API key

[robertjdominguez]

Description

• Fixed missing OpenAI API key configuration for TypeScript connector
• Reorganized environment variables for better readability
• Added proper CI/CD environment variable mapping

Previously, the TypeScript connector was configured but couldn't access the OpenAI API after rolling and redacting the old key:

const openai = new OpenAI({
  apiKey:
    process.env.OPENAI_API_KEY ||
    "[REMOVED]",
});

The environment variable OPENAI_API_KEY wasn't being passed through the connector configuration or CI pipeline, causing the embedding function to fall back to a placeholder value.

Now the OpenAI API key flows properly through all layers:

envMapping:
  OPENAI_API_KEY:
    fromEnv: APP_TS_OPENAI_API_KEY

environment:
  OPENAI_API_KEY: $APP_TS_OPENAI_API_KEY

This ensures the transformQueryIntoEmbedding function can actually generate embeddings instead of failing silently. The TypeScript connector is critical for semantic search functionality - without proper OpenAI access, document similarity matching would be broken.

Also cleaned up the environment variable ordering in the playground service for consistency, moving ANTHROPIC_KEY to the top since it's the primary LLM configuration.
