Add a command to queue messages for existing sessions (#39092)

## What changed

- Add `codex queue --thread <THREAD> --message <TEXT>` to submit a text message through the `thread/queue/add` app-server API.
- Resolve active sessions by UUID or exact name across interactive, exec, and custom sources, and reject ambiguous names.
- Support local and explicit remote app servers while reporting incompatible servers and configuration overrides instead of silently changing the target.
- Reject empty messages and image attachments.

## Testing

- Add CLI coverage for remote submission, validation, unsupported servers, and local-daemon routing.
- Add session lookup and queue tests for stale, non-interactive, custom, and duplicate session names.
