docs: swap Ollama example for Infron LLM gateway in custom LLM provider doc (#1477)

* docs: swap Ollama functional example for Infron LLM gateway

Introduces the LLM gateway concept (single OpenAI-compatible endpoint,
unified billing, fallbacks), replaces the Ollama walkthrough with an
Infron config, and links out to Infron's signup + quickstart per their
reciprocal doc in their OpenWork page.

* docs: frame Infron as hosted gateway vs LiteLLM starting point

Link to Infron's LiteLLM integration page as the canonical open-source
gateway reference, and position Infron as the OpenRouter-style hosted
gateway that sits on top: one key, unified billing, provider fallbacks.

* docs: drop OpenRouter comparison, pitch Infron directly for dev ergonomics

* docs: drop em dashes, loosen Infron pitch to devrel voice

* docs: add Infron model picker + active session screenshots

-### Functional example: Ollama (Qwen3 8B)
+### Functional example: an LLM gateway (Infron)
 
-This setup a local [Ollama](https://docs.ollama.com/api/openai-compatibility) instance running `qwen3:8b`. 
-Ollama's OpenAI-compatible endpoint requires an API key but ignores the value, so paste anything (for example `ollama`) into the `API key / credential` field when creating the provider.
+An LLM gateway is one OpenAI-compatible endpoint that fans out to many model providers. If you want to run the routing yourself, [LiteLLM](https://infron.ai/docs/frameworks-and-integrations/litellm) is a good starting point. [Infron](https://infron.ai) is the hosted option: one API key gets you every model in its [marketplace](https://infron.ai/models) with automatic provider fallbacks and a single invoice, so adding a new LLM to OpenWork is just another entry under `models`.

+Grab a key from the [API Keys dashboard](https://infron.ai/dashboard/apiKeys). If you don't have an account yet, sign up at [infron.ai/login](https://infron.ai/login) and their [quickstart](https://infron.ai/docs/overview/quickstart/text) walks you through your first request.

+Add more entries under `models` to expose other routes the gateway supports (e.g. `openai/gpt-5.4`, `google/gemini-2.5-flash`).
 
 ## When to use a cloud provider
 
-We recommend using Cloud-bsaed provider when the setup is meant to be shared across an org or team. Otherwise, doing it directly in desktop is easier.
+Use a Cloud provider when the setup is meant to be shared across an org or team. For solo use, configuring it directly in the desktop app is simpler.
