feat: add openAiStrictToolMode setting for OpenAI-compatible providers

Closes: #11011

Description

This PR addresses the issue where kie.ai (and similar OpenAI-compatible providers using Gemini 3 Pro) fails to work properly because the OpenAI provider adds strict: true and schema modifications that these providers do not support.

Key implementation details:

• Added a new openAiStrictToolMode setting to the OpenAI provider settings schema
• Modified convertToolsForOpenAI() in base-provider.ts to accept a useStrictMode parameter
• When strict mode is disabled, tool definitions are passed through without modifications (no strict: true, no additionalProperties: false, no required array modifications)
• The setting defaults to true (enabled) for backward compatibility with standard OpenAI API
• Added a checkbox in the OpenAI-Compatible settings UI to toggle this setting

Trade-offs:

• Opted for a simple boolean toggle rather than more granular control, as this covers the common use case of providers that support standard OpenAI function calling but not strict mode

Test Procedure

1. All existing tests pass (48 openai.spec.ts tests, 15 base-provider.spec.ts tests)
2. Type checking passes across all packages
3. Manual testing can be performed by:
   • Configure an OpenAI-Compatible provider pointing to kie.ai
   • Disable the "Enable strict tool mode" checkbox
   • Verify that tool calls work correctly

Screenshots / Videos

N/A - This is a settings addition. The new checkbox appears in the OpenAI-Compatible provider settings panel.

Documentation Updates

• No documentation updates are required.
• Yes, documentation updates are required. (The new setting should be documented for users configuring OpenAI-compatible providers like kie.ai)

Additional Notes

The kie.ai API documentation shows it supports standard OpenAI function calling with the tools array format, but does not support OpenAI's strict mode. This setting allows users to disable strict mode for such providers while maintaining backward compatibility for standard OpenAI API usage.

Important

Introduces openAiStrictToolMode setting to handle OpenAI-compatible providers not supporting strict mode, with UI and internationalization updates.

• Behavior:
  • Adds openAiStrictToolMode setting to OpenAI provider settings schema in provider-settings.ts.
  • Modifies convertToolsForOpenAI() in base-provider.ts to accept useStrictMode parameter, bypassing strict mode modifications when disabled.
  • Defaults to true for backward compatibility.
  • Adds UI checkbox in OpenAICompatible.tsx to toggle this setting.
• Internationalization:
  • Updates settings.json in multiple locales (e.g., tr, vi, zh-CN, zh-TW) to include translations for the new setting.
• Testing:
  • All existing tests pass, including 48 in openai.spec.ts and 15 in base-provider.spec.ts.
  • Manual testing instructions provided for OpenAI-Compatible providers.

Review completed. No issues found.

The implementation correctly adds an openAiStrictToolMode setting that allows users to disable OpenAI strict mode for tool definitions. This enables compatibility with providers like kie.ai that don't support strict mode.

Verified:

• Type definition properly added to Zod schema
• Setting defaults to true for backward compatibility
• Setting applied in all 4 code paths (streaming/non-streaming, regular/O3)
• UI checkbox and i18n strings properly added
• All 17 locale translations added correctly (ca, de, es, fr, hi, id, it, ja, ko, nl, pl, pt-BR, ru, tr, vi, zh-CN, zh-TW)
