- i18n: complete remaining internationalization across the UI

- Locales: add and align keys (common.enterValidValue, apiKeyInput.*, jsonEditor.*, claudeConfig.*); fix zh common.unknown mapping
- ProviderForm: localize labels/placeholders/hints/errors; unify JSON/auth validation to providerForm.*; add wizard CTA for Codex custom with i18n; cancel uses common.cancel
- CodexConfigEditor: i18n for quick wizard, labels/placeholders/hints, common config modal (title/help/buttons)
- ClaudeConfigEditor: i18n for main label, common-config toggle/button, modal title/help, footer buttons
- EndpointSpeedTest: localize failed/noEndpoints/done and aria labels
- ApiKeyInput: i18n for placeholder and show/hide aria
- JsonEditor: i18n linter messages
- PresetSelector: remove hardcoded defaults, use i18n keys
- UpdateBadge: i18n close aria
- Build/typecheck: pass; scan shows no visible hardcoded Chinese strings outside locales
