test(logs): give the 4 MiB archive segment test a 60 s budget (#19877)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native run logs migrate into a bounded object-storage archive
(#19719)
> - One integration test migrates a 4 MiB log and reads it back across a
segment boundary against embedded PostgreSQL
> - On loaded CI runners it exceeds Vitest's 15 s default, so `General
tests (server (9/12))` fails on unrelated PRs
> - This pull request gives that one test an explicit 60 s budget
> - The benefit is that unrelated PRs stop failing on a timing-only
timeout, and the test keeps its exact-bytes assertions

## Linked Issues or Issue Description

Refs #19719 (the test's origin).

**Problem**
`native-log-archive.integration.test.ts > preserves exact bytes across
the bounded archive segment boundary` times out at 15 s on CI. On
2026-11-07 it failed on at least eight unrelated branches, among them
`fix/skill-cache-lock-owner-proof`, `chat-eval/master-candidate`,
`fix/subtasks-own-workspace` and `feat/owner-gone-prover` (three
attempts).

**Expected behavior**
The test passes when the code is correct, regardless of runner load.

**Impact**
It blocks merges on unrelated PRs and wastes reruns.

## What Changed

- Give that single test an explicit 60 s timeout, with a comment that
names the reason. No assertion changes.

## Verification

- `npx vitest run src/services/native-log-archive.integration.test.ts`
(in `server/`): 15 tests pass locally.
- The CI shard `General tests (server (9/12))` should pass on this PR.

## Risks

- Low risk. This is a test-only timeout change. A real hang still fails,
after 60 s.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, in Claude Code with
tool use and code execution.
