cthomas d992aa0df4 fix: non-streaming conversation messages endpoint (#9159) ...

* fix: non-streaming conversation messages endpoint

**Problems:**
1. `AssertionError: run_id is required when enforce_run_id_set is True`
   - Non-streaming path didn't create a run before calling `step()`

2. `ResponseValidationError: Unable to extract tag using discriminator 'message_type'`
   - `response_model=LettaStreamingResponse` but non-streaming returns `LettaResponse`

**Fixes:**
1. Add run creation before calling `step()` (mirrors agents endpoint)
2. Set run_id in Redis for cancellation support
3. Pass `run_id` to `step()`
4. Change `response_model` from `LettaStreamingResponse` to `LettaResponse`
   (streaming returns `StreamingResponse` which bypasses response_model validation)

**Test:**
Added `test_conversation_non_streaming_raw_http` to verify the fix.
