Delete an LLM

Permanently deletes an LLM configuration. This operation cannot be undone and removes the LLM record and securely deletes stored credentials.

IMPORTANT: This does NOT invalidate or delete any previously generated content using this LLM - existing generations remain accessible. Requires DELETE_LLM_OWN permission for LLMs you own (or DELETE_LLM_ANY for admin users).
