Celia Chen 0dd822264a [app-server-test-client] add send-followup-v2 (#7271) ...

Add a new endpoint that allows us to test multi-turn behavior.

Tested with running:
```
RUST_LOG=codex_app_server=debug CODEX_BIN=target/debug/codex \
      cargo run -p codex-app-server-test-client -- \
      send-follow-up-v2 "hello" "and now a follow-up question"
```
