The OpenAI backend passed tool_choice through raw while the Anthropic and
Gemini backends translate Honcho's canonical vocabulary to their native
form. On a mixed-provider fallback chain (e.g. Gemini primary -> OpenAI
backup), a canonical "any" reached OpenAI unchanged and was rejected as an
invalid param, since OpenAI only accepts none/auto/required.
Add a _convert_tool_choice to the OpenAI backend mirroring the others so a
single TOOL_CHOICE value resolves correctly regardless of which provider a
fallback lands on. "any"/"required" -> "required", auto/none pass through,
a tool-name string or {"name": ...} dict -> a function selection.
