Benjamin Carlsson 1da2aefe00 Enable cross-backend session switching in the TUI (#58457) ...

## Why

The session picker can list conversations from multiple backends, but selecting a conversation owned by another backend was rejected.

## What changed

- Resume selected conversations through their owning backend, preparing the destination before replacing the current conversation. Preserve drafts and restore the destination's settings, account state, model catalog, and workspace services.
- Block backend switches during an active turn and retain the current conversation when destination preparation fails.
- Queue background backend requests until that backend is displayed, removing requests that are resolved or disconnected. Isolate background events from the displayed conversation while continuing to deliver notifications to a background voice session.
- Track backend ownership for thread detachment, startup results, and reconnect attempts.
- Remove the `yaml-rust` advisory exception from `codex-rs/deny.toml`.

## Testing

Add regression coverage for backend handoff errors, detaching through the source connection, clearing stale provider errors, deferred request delivery and cleanup, and voice-session closure on a background backend.
