fix: address quick-xml security advisories (#30941)

## Why

The `cargo-deny` job on `main` began failing after
[RUSTSEC-2026-0194](https://rustsec.org/advisories/RUSTSEC-2026-0194)
and
[RUSTSEC-2026-0195](https://rustsec.org/advisories/RUSTSEC-2026-0195)
flagged the workspace `quick-xml 0.38.4`. Both denial-of-service issues
are fixed in `quick-xml 0.41.0`.

A `quick-xml 0.39.4` copy must temporarily remain because the latest
`plist` and `wayland-scanner` releases have not adopted 0.41 yet.
Neither retained path accepts attacker-controlled XML at runtime:
`plist` does not exercise the affected APIs, and `wayland-scanner`
parses trusted protocol definitions at build time. Compatible upstream
bumps are already open in
[rust-plist#191](https://github.com/ebarnard/rust-plist/pull/191) and
[wayland-rs#938](https://github.com/Smithay/wayland-rs/pull/938).

## What changed

- Upgrade the workspace `quick-xml` dependency used by `codex-protocol`
to 0.41.0.
- Refresh `Cargo.lock` and `MODULE.bazel.lock`; this also updates
`plist` to 1.9.0 and `wayland-scanner` to 0.31.10.
- Add synchronized, temporary `cargo-deny` and `cargo-audit` exceptions
for the trusted `quick-xml 0.39.4` paths, with both upstream releases
recorded as the removal condition.

## Testing

- `cargo deny check`
- `just test -p codex-protocol` (238 tests)
- `just bazel-lock-check`
