🪶 feat: Add Support for Azure OpenAI Base URL (#1596)

Browse source 
* refactor(extractBaseURL): add handling for all possible Cloudflare AI Gateway endpoints

* chore: added endpointoption todo for updating type and optimizing handling app-wide

* feat(azureUtils):
- `genAzureChatCompletion`: allow optional client pass to update azure property
- `constructAzureURL`: optionally replace placeholders for instance and deployment names of an azure baseURL
- add tests for module

* refactor(extractBaseURL): return entire input when cloudflare `azure-openai` suffix detected
- also add more tests for both construct and extract URL

* refactor(genAzureChatCompletion): only allow omitting instance name if baseURL is not set

* refactor(initializeClient): determine `reverseProxyUrl` based on endpoint (azure or openai)

* refactor: utitlize `constructAzureURL` when `AZURE_OPENAI_BASEURL` is set

* docs: update docs on `AZURE_OPENAI_BASEURL`

* fix(ci): update expected error message for `azureUtils` tests

```bash
# .env file
AZURE_OPENAI_BASEURL=https://${INSTANCE_NAME}.openai.azure.com/openai/deployments/${DEPLOYMENT_NAME}
# Cloudflare example
AZURE_OPENAI_BASEURL=https://gateway.ai.cloudflare.com/v1/ACCOUNT_TAG/GATEWAY/azure-openai/${INSTANCE_NAME}/${DEPLOYMENT_NAME}
```

- Can include `${INSTANCE_NAME}` and `${DEPLOYMENT_NAME}` placeholders or specific credentials.
- Example: "https://gateway.ai.cloudflare.com/v1/ACCOUNT_TAG/GATEWAY/azure-openai/${INSTANCE_NAME}/${DEPLOYMENT_NAME}"
- [More info about `AZURE_OPENAI_BASEURL` here](./ai_setup.md#using-a-specified-base-url-with-azure)
> Note: as deployment names can't have periods, they will be removed when the endpoint is generated.
