test: use a common fake clock baseline (#15052)

## Summary

Child of #15050. Give every root Vitest test the same named fake-clock
baseline and express scenario time as relative movement from that
baseline.

```ts
const TEST_SYSTEM_TIME = Date.parse('2024-06-15T12:00:00Z')
```

- reduces test-local `vi.setSystemTime()` calls from 44 to 7
- replaces arbitrary Unix-adjacent timestamps and unrelated calendar
dates with `Date.now()`-relative fixtures
- uses `vi.advanceTimersByTime()` when elapsed time, rather than a
wall-clock jump, is the behavior under test
- retains six non-firing wall-clock jumps where advancing timers would
execute scheduled work and change the scenario
- retains one explicit July 2026 clock for calendar-boundary filtering
- makes a template-freshness fixture relative to the baseline instead of
depending on the actual current date
- aligns a module-scoped workspace-token expiry with the deterministic
test clock

## Baseline choice

The most frequent exact timestamp was `1_000_000` ms (five calls),
equivalent to `1970-01-01T00:16:40Z`. That value was common but
arbitrary.

June 15, 2024 was the most common meaningful calendar anchor: four
date-oriented setups used that day. Noon UTC is explicit, stable, and
compatible with the root project's existing `TZ=UTC` configuration.

## Results

| Metric | Before | After | Change |
|---|---:|---:|---:|
| `vi.setSystemTime()` calls | 44 | 7 | −37 (−84%) |
| Files containing those calls | 14 | 3 | −11 (−79%) |
| Root tests passed | 15,892 | 15,892 | No regression |
| Root tests skipped | 8 | 8 | No change |

The first full run exposed one hidden real-date dependency in
`templateRankingStore.test.ts`: a hardcoded January 2024 template was
only “very old” relative to the present day. It is now represented as
three years before `Date.now()`, matching the behavior the assertion
describes.

## Validation

- `pnpm test:unit`: 1,159 files passed; 15,892 tests passed; 8 skipped
- `pnpm lint`
- `pnpm typecheck`
- oxfmt and type-aware Oxlint on all changed files
- pre-push `pnpm knip --cache`
