Remove Anthropic API key authentication support

API key auth only provides short-lived session tokens (8hrs or until
session restart) with no refresh mechanism, unlike OAuth which persists
via .credentials.json. Remove the non-functional API key settings UI
and all supporting code (frontend state, Tauri commands, keyring
storage, container env var injection, and fingerprint-based recreation
checks) to avoid user confusion.
