fix(server): load the mocked module graph once in the closed-workspace issue route suite (#12470)

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The server tests cover issue routes and execution workspace state
> - The closed-workspace route suite reloads a mocked module graph
before each test
> - CPU contention can bind one test to the real service and hide a 500
response
> - This pull request loads the mocked graph once and checks exact
success statuses
> - The benefit is a stable suite that detects route failures instead of
accepting them

## Linked Issues or Issue Description

**What happened?**

The closed-workspace issue route suite reloaded and unmocked the module
graph before each test. Under CPU contention, a route could bind to the
real execution-workspaces service. The request then returned `500`,
while a weak assertion accepted the result.

**Expected behavior**

The suite must use the configured service mocks for every test. Each
success case must assert its exact expected HTTP status.

**Steps to reproduce**

1. Run the closed-workspace route suite many times in parallel.
2. Use CPU contention during the run.
3. Observe intermittent failures or weak assertions that accept `500`
responses.

**Paperclip version or commit**

Commit `0d5686b942f1d1366112cb922f95e5c8622bb9a6`.

**Deployment mode**

Built from source with the server test runner.

**Installation method**

Built from source.

**Agent adapter(s) involved**

Not adapter-specific.

**Database mode**

Not database-related.

**Additional context**

This pull request relates to
[#11472](https://github.com/paperclipai/paperclip/pull/11472). It does
not change product code.

## What Changed

- Load the mocked service graph once per file with `hoistModuleGraph`.
- Remove the per-test module reset and unmock cycle.
- Assert exact success statuses for the three affected responses.
- Add the missing `refreshReopenPendingConsumption` mock.
- Use one named timeout constant for every `vi.waitFor` call.
- Replace `setImmediate` barriers with fake-timer advances.

## Verification

- `npx vitest run --project @paperclipai/server
server/src/__tests__/issue-closed-workspace-routes.test.ts` passes 12 of
12 tests locally.
- A 200-sample sweep with 20 parallel copies passed with zero failures.
- An independent 100-sample sweep with 20 parallel copies passed with
zero failures.
- `npx tsc --noEmit -p server` reports the same 61 pre-existing errors
with and without this change.
- GitHub Actions must run the full server suite for final verification.

## Risks

Low risk. This pull request changes one test file and does not change
product code. The stricter assertions can expose a real route failure
that the old suite hid.

## Model Used

Codex, GPT-5, tool use and code review assistance. The exact context
window and reasoning mode are not available in this handoff.
