Michael BolinandGitHub a73efab8dd fix: address flakiness in thread_resume_rejoins_running_thread_even_with_override_mismatch (#12381) ...

## Why
`thread/resume` responses for already-running threads can be reported as
`Idle` even while a turn is still in progress. This is caused by a
timing window where the runtime watch state has not yet observed the
running-thread transition, so API clients can receive stale status
information at resume time.

Possibly related: https://github.com/openai/codex/pull/11786

## What
- Add a shared status normalization helper, `resolve_thread_status`, in
`codex-rs/app-server/src/thread_status.rs` that resolves
`Idle`/`NotLoaded` to `Active { active_flags: [] }` when an in-progress
turn is known.
- Reuse this helper across thread response paths in
`codex-rs/app-server/src/codex_message_processor.rs` (including
`thread/start`, `thread/unarchive`, `thread/read`, `thread/resume`,
`thread/fork`, and review/thread-started notification responses).
- In `handle_pending_thread_resume_request`, use both the in-memory
`active_turn_snapshot` and the resumed rollout turns to decide whether a
turn is in progress before resolving thread status for the response.
- Extend `thread_status` tests to validate the new status-resolution
behavior directly.

## Verification
- `cargo test -p codex-app-server
suite::v2::thread_resume::thread_resume_rejoins_running_thread_even_with_override_mismatch`
