Remove hardcoded translation API key and use env var

[esclipse]

Motivation

• Remove a hardcoded API key embedded in the server route to eliminate a security and operational risk.
• Allow the translation service credential to be rotated and scoped per environment without a code change.

Description

• Replace the hardcoded key in app/api/translate/route.ts with a runtime lookup of process.env.GEEKAI_API_KEY.
• Return a 500 JSON error when GEEKAI_API_KEY is missing to fail fast and clearly in misconfigured deployments.
• Instantiate the OpenAI client inside POST using the environment-provided apiKey and retain the baseURL: 'https://geekai.co/api/v1' configuration.

Testing

• No automated tests were executed for this change.
• Local runtime checks performed: file updated and committed successfully using git commit (no test suite run).
