app-server: prepare to run initialized rpcs concurrently (#17372)

Browse Source 
## Summary

- Refactors `MessageProcessor` and per-connection session state so
initialized service RPC handling can be moved into spawned tasks in a
follow-up PR.
- Shares the processor and initialized session data with
`Arc`/`OnceLock` instead of mutable borrowed connection state.
- Keeps initialized request handling synchronous in this PR; it does
**not** call `tokio::spawn` for service RPCs yet.

## Testing

- `just fmt`
- `cargo test -p codex-app-server` *(fails on existing hardening gaps
covered by #17375, #17376, and #17377; the pipelined config regression
passed before the unrelated failures)*
- `just fix -p codex-app-server`
