Michael Bolin d54493ba1c test: stabilize app-server path assertions on Windows (#19604) ...

## Why

Windows can represent the same canonical local path with either a normal
drive path or a verbatim device path prefix. The failure pattern that
motivated this PR was an assertion diff like `C:\...` versus
`\\?\C:\...`: different spellings, same file.

That became visible while validating the permissions stack above this
PR. The stack increasingly routes paths through `AbsolutePathBuf`, which
normalizes supported Windows device prefixes, while several existing
tests still built expected values directly with
`std::fs::canonicalize()` or compared `AbsolutePathBuf::as_path()` to a
raw `PathBuf`. On Windows, that can make tests fail because the two
sides choose different textual forms for an otherwise equivalent
canonical path.

This PR is intentionally split out as the bottom PR below #19606. The
runtime permissions migration should not carry unrelated Windows test
stabilization, and reviewers should be able to verify this as a
test-only change before looking at the larger permissions changes.

## Failure Modes Covered

- `conversation_summary` expected rollout paths were built from raw
canonicalized `PathBuf`s, while app-server responses could carry
`AbsolutePathBuf`-normalized paths.
- `thread_resume` compared returned thread paths directly to previously
stored or fixture paths, so a verbatim-prefix spelling could fail an
otherwise correct resume.
- `marketplace_add` compared plugin install roots through `as_path()`
against raw canonicalized paths, reproducing the same `C:\...` versus
`\\?\C:\...` mismatch in both app-server and core-plugin coverage.

## What Changed

- In `app-server/tests/suite/conversation_summary.rs`, normalize both
expected rollout paths and received `ConversationSummary.path` values
through `AbsolutePathBuf` before comparing the full summary object.
- In `app-server/tests/suite/v2/thread_resume.rs`, normalize both sides
of thread path comparisons before asserting equality. This keeps the
tests focused on whether resume returned the same existing path, not
whether Windows used the same string spelling.
- In `app-server/tests/suite/v2/marketplace_add.rs` and
`core-plugins/src/marketplace_add.rs`, compare install roots as
`AbsolutePathBuf` values instead of comparing an absolute-path wrapper
to a raw canonicalized `PathBuf`.

## Behavior

This PR does not change production app-server or marketplace behavior.
It only changes tests to assert semantic path identity across Windows
path spelling variants. It also leaves API response values untouched;
the normalization happens inside assertions only.

## Verification

Targeted local checks run while extracting this fix:

- `cargo test -p codex-app-server
get_conversation_summary_by_thread_id_reads_rollout`
- `cargo test -p codex-app-server
get_conversation_summary_by_relative_rollout_path_resolves_from_codex_home`
- `cargo test -p codex-app-server
thread_resume_prefers_path_over_thread_id`

Windows-specific confidence comes from the Bazel Windows CI job for this
PR, since the failure is platform-specific.

## Docs

No docs update is needed because this is test-only infrastructure
stabilization.
