feat(settings): add 'Apply to Claude Code extension' toggle

- Apply immediately on save (write or remove primaryApiKey)
- Honor setting on provider switch (enabled: write for non-official, remove for official; disabled: no auto writes)
- Remove per-provider Claude plugin buttons from ProviderList
- Upsert primaryApiKey=any preserving other fields; respect override dir
- Add zh/en i18n for the new setting
