[BUG] OpenAI Compatible - Claude Opus 4.7 - `temperature` deprecated

[marty-a11y]

Describe the bug
Any attempt to use claude-opus-4-7 through the OpenAI Compatible provider results in an error about temperature being deprecated.

The following error occurs:

Error: `OpenAI completion error: 400 litellm.BadRequestError: BedrockException - {\"message\":\"The model returned the following errors: {\\\"type\\\":\\\"error\\\",\\\"request_id\\\":\\\"req_p2msrdcxdgpww2tqhgwewtvomrkhc2l2pe5xdananom42vw6tqja\\\",\\\"error\\\":{\\\"type\\\":\\\"invalid_request_error\\\",\\\"message\\\":\\\"`temperature` is deprecated for this model.\\\"}}\"}`

To Reproduce
Steps to reproduce the behavior:

1. Set up OpenAI compatible with claude-opus-4-7
2. Send any prompt.

Expected behavior
No error from the API

What version of zoo are you running
3.54.1

Additional context
Unfortunately I cannot share the server nor the credentials I'm using. But I'm told our server just "forwards" to upstream models, so my guess is it goes directly to Claude.

It may also be helpful to know that claude-opus-4-6, using otherwise identical settings, is working fine.

Opened #233. The OpenAI-Compatible handler always sent `temperature`; it now honors the model's `supportsTemperature` flag (already respected by other providers) and omits it when set to false. As a workaround until merge, you can toggle Supports temperature → off on the model in settings.
