feat(settings): Codex Bağlama, on by default

Settings → Codex Bağlama runs the bundled bridge for an OpenAI Codex install on
the same computer: the IDE's models and combos appear in Codex and switching
models keeps the conversation. The IDE points Codex's openai_base_url at the
bridge only after the bridge answers, keeps it running across logins, and
removes every trace when the setting is turned off. A Codex that already uses
another base URL is left untouched.
