Closes #230

Added validation for OpenRouter API key

Current code (before PR):

• No validation for OpenRouter API key

PR Code changes:

• In src/lib/ai.ts, created new function validateApiKey() which validates both OpenAI and OpenRouter keys, by calling validateOpenAiApiKey() or validateOpenRouterApiKey()
• In src/lib/ai.ts, create new function validateOpenRouterApiKey(), which uses response from https://openrouter.ai/docs#limits to check if OpenRouter API key is valid
• In src/components/Message/AppMessage/Instructions.tsx, replaced call of validateOpenAiApiKey() with validateApiKey()
• In src/components/PreferencesModal.tsx, replaced call of validateOpenAiApiKey() with validateApiKey()

Testing:

Sure, I can do that for future PRs. Do you need me to recreate my current PRs? (this one or PR#308)

[tarasglek]

@humphd ok to accept this one as is?

[humphd]

A few small things, this is looking good.

[kliu57]

@humphd Made the three code fixes as suggested.

Also, I noticed in src/hooks/use-models.tsx there is a call to queryModels(). Now that my OpenRouter validation is not done inside of queryModels() anymore, this particular call to queryModels() will not be able to validate any OpenRouter keys. Is this something of concern?

[humphd]

@kliu57 This needs to be rebased to pick up the change we just landed in src/lib/ai.ts.

I think the call to queryModels() in src/hooks/use-models.tsx` doesn't need to be validated, since it will fail if the key is wrong anyway. We only really care about warning people and validating when we are setting the key during setup.

Great work @kliu57. I hope you'll keep working ChatCraft in the future.
