Michael Bolin ff05532723 refactor: narrow async lock scopes (#18418) ...

## Why

This is part of the follow-up work from #18178 to make Codex ready for
Clippy's
[`await_holding_lock`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_lock)
/
[`await_holding_invalid_type`](https://rust-lang.github.io/rust-clippy/master/index.html#await_holding_invalid_type)
lints.

This bottom PR keeps the scope intentionally small:
`NetworkProxyState::record_blocked()` only needs the state write lock
while it mutates the blocked-request ring buffer and counters. The debug
log payload and `BlockedRequestObserver` callback can be produced after
that lock is released.

## What changed

- Copies the blocked-request snapshot values needed for logging while
updating the state.
- Releases the `RwLockWriteGuard` before logging or notifying the
observer.

## Verification

- `cargo test -p codex-network-proxy`
