* Fix OpenAIResponsesAgentClient endpoint to include agentName in path (#5324)
The sample OpenAIResponsesAgentClient used '/v1/' as the endpoint, which
routes to the multi-agent endpoint requiring agent.name in the request body.
However, AsIChatClient(agentName) maps agentName to the model field, not
agent.name, causing HTTP 400 errors on OpenAI-compatible endpoints.
Changed the endpoint to '/{agentName}/v1/' to match the pattern used by
OpenAIChatCompletionsAgentClient, routing to the single-agent endpoint
where no agent.name body field is needed.
Added regression test verifying that the model field alone is insufficient
for agent resolution on the multi-agent endpoint.

* Address review feedback for #5324
- URL-escape agentName in OpenAIResponsesAgentClient endpoint path to
handle reserved characters safely
- Add per-agent MapOpenAIResponses() calls in AgentHost so the sample
host serves the /{agentName}/v1/responses routes the client now targets
- Replace brittle Assert.Contains("agent.name") assertions with stable
machine-readable error code assertion ("missing_required_parameter")

* Address additional review feedback for #5324
- Apply Uri.EscapeDataString to OpenAIChatCompletionsAgentClient endpoint
for consistency with OpenAIResponsesAgentClient
- Map OpenAI Responses and ChatCompletions endpoints for all builder-based
agents (chemist, mathematician, literator, science workflows) so every
discoverable agent is reachable via the single-agent endpoint path
