Delete .env

Expose ability to configure a custom AI API key in UI while preserving default key usage; store custom config locally and adapt requests to use either the default provider or user-provided endpoint/key/model. Key remains accessible in code for GPT-OSS IP-locked integration, but a new Custom API path allows safer testing with user-supplied credentials.
